The filter is named after Kalman because he published his results in a more prestigious journal and his work was more general and complete. International Journal of Adaptive Control and Signal Processing. A flatness-based control approach for induction motors, 5. UKF is a derivative-free state estimation method of high accuracy. (36) a controller that satisfies the flatness properties (and thus it can be also expressed as a function of the flat outputs and their derivatives) is defined as follows: where isq* and isd* denote current setpoints. In the control of robotic manipulators, which is actually control of the DC motors that rotate the robot's joints, the angle of each joint is usually measured with the use of an optical encoder. The estimation error covariance matrix P∈R3×3 and the KF gain K∈R3×1 were used in Eq. The Extended Kalman Filter is applicable to nonlinear electric motor models, such as the induction motor described in Sections 3 and 4. The time-varying Kalman filter is a generalization of the steady-state filter for time-varying systems or LTI systems with nonstationary noise covariance. (8) can be written in the Brunovsky (canonical) form: where v=f̄(x,t)+ḡ(x,t)u. The paper has shown that in the design of state estimation-based control for electric motors the following should be taken into account: (i) for linear electric motor models subject to Gaussian measurement or process noise the Kalman Filter is the optimal state estimator, since it results in minimization of the trace of the estimation error's covariance matrix, (ii) for nonlinear electric motor models, subject to Gaussian noise one can use the generalization of the Kalman Filter as formulated in terms of the Extended Kalman Filter. For nonlinear systems, subject to Gaussian noise one can use the generalization of the Kalman Filter as formulated in terms of the Extended Kalman Filter (EKF). Today the Kalman filter is used in Tracking Targets (Radar), location and navigation systems, control systems, computer graphics and much more. As BLDC motors are non-linear systems, Extended Kalman Filter (EKF), an advanced version of the Kalman filter has been used for designing the control algorithm for the motor. The linear model of the DC motor shown in Fig. Moreover, using Eq. where x^−(k) is the estimation of the state vector using measurements up to time instant k−1, x^(k) is the estimation of the state vector using measurements up to time instant k, P is the covariance matrix of the estimation error, R is the measurement noise covariance matrix and Q is the process noise covariance matrix.

For the motor model of Eq. 5. Kalman Filter-based control for DC and induction motors can have several applications for the design of industrial and robotic systems of improved performance. View or download all the content the society has access to. A model of the feedback system using DC motor consisting of rotational speed and armature current as states is used in the state-space form. This means that all system dynamics can be expressed as a function of the flat output and its derivatives, therefore the state vector and the control input can be written as x(t)=φ(y(t),ẏ(t),⋯,y(r)(t)) and u(t)=ψ(y(t),ẏ(t),⋯,y(r)(t)). Linear Regression method with stepwise model will be used to represent the correlation between the distance of the line laser in the image and the actual distance of the obstacle in real world. 2010] Boizot, N., Busvelle, E., Gauthier, J.-P.

For nonlinear electric motor models, subject to Gaussian noise one can use the Extended Kalman Filter. InSection7 the efficiency of the above mentioned Kalman Filter-based control schemes, for both the DC and induction motor models, is tested through simulation experiments. 2.2. The parameter λ is a scaling parameter. The basic sigma-point approach can be described as follows: A set of weighted samples (sigma-points) are deterministically calculated using the mean and square-root decomposition of the covariance matrix of the prior random variable. Using this plan gives the following two features. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. As a minimal requirement the sigma-point set must completely capture the first and second order moments of the prior random variable. with the following notations L: armature inductance, I: armature current, ke: motor electrical constant, R: armature resistance, V: input voltage, taken as control input, J: motor inertia, ω: rotor rotation speed, kd: mechanical dumping constant, Γd: disturbance torque. Abstract: This work deals with the tuning of an Extended Kalman Filter for sensorless control of induction motors for electrical traction in automotive. The resulting expressions create first order approximations of φ and γ. In (Akin et al. Here, it is shown that a slight modification of the linear-quadratic-gaussian Kalman filter model allows the on-line estimation of optimal control by using reinforcement learning and overcomes this difficulty. A complex-valued model is adopted that simultaneously allows a simpler observability analysis of the system and a more effective state estimation. The noise is typical of DC motor brush noise. Introduction There is increasing demand for dynamical systems to become more realizable and more cost-effective. The Kalman filter is an algorithm that estimates the state of a system from measured data. (28) and Eq. Create a link to share a read only version of this article with your colleagues and friends. The system of Eq. The performance of standard versus rank regression is compared for both linear and nonlinear forward operators (also known as observation operators) using a low-order model. Standard regression, in combination with either a rank histogram filter or an ensemble Kalman filter in observation space, produces the best results in other situations. It will be shown that it is possible to implement state estimation for the electric motor using measurements only the rotation angle θ and of the stator currents isa and isb. The covariance matrix of the measurement noise was defined E{v(i)vT(j)}=Rδ(i−j), with diagonal elements rii=10−2. ^ ∣ − denotes the estimate of the system's state at time step k before the k-th measurement y k has been taken into account; ∣ − is the corresponding uncertainty. The Kalman filter is a special kind of observer which provides optimal estimation of the system states based on least-square techniques. Additionally, controllers for nonlinear DC motor models have been developed. This paper presents the application of Extended Kalman Filter to the speed control of a BLDC motor. (41) one can apply state feedback control. The aim of this paper is to decrease the execution time of EKF modeling of a six-phase induction motor. For the outer speed and flux control design the stator currents are treated as new control inputs and the system behavior is described by Eq. For more information view the SAGE Journals Article Sharing page. (29), then one can succeed ψrd(t)→ψrdref(t). That means, rotor flux and stator currents estimated by KF are used as inputs Typically, these take on the form of a simple weighted sample mean and covariance calculations of the posterior sigma points. The Unscented Kalman Filter can be used for state estimation of nonlinear electric motors, such as the induction motor analyzed in Sections 3 and 4. Further, this is used for modeling the control of movements of central nervous systems. (, Wai & Chang 2004] Wai, R.J., Chang, H.H. Extended State Observers, Unknown Input Observers or Perturbation Observers) and on their use within a Kalman Filter framework (Miklosovitch et al 2006), (Kwon Chung 2003). Comparison between the estimated and the real output measurements enables the detection of failures in the motor's components. The sections on “Control Process”, “Real Time Implementation” and “Kalman Filter Observer and Prediction” in the introductory chapters explain how to practically implement, in real time, the discretized control with all three types of AC motors. Regarding (ii), additive disturbances and parametric changes can be identified with the use of Kalman Filters that operate as disturbance observers (see work on Kalman Filtering and disturbance observers in (Rigatos 2011)). For most ensemble algorithms commonly applied to Earth system models, the computation of increments for the observation variable ensemble can be treated as a separate step from computing increments for the state variable ensemble.

The Kalman filter keeps track of the estimated state of the system and the variance or uncertainty of the estimate. The new control inputs of the system are considered to be vsd, vsq, and are associated to the d−q frame voltages vd and vq, respectively. Moreover, state estimation-based control is developed for the induction motor model using a nonlinear flatness-based controller and the state estimation that is provided by the Extended Kalman Filter. The sampling period was taken to be Ts=0.01sec. The Kalman filter is widely used in present robotics such as guidance, navigation, and control of vehicles, particularly aircraft and spacecraft.

There are several results on disturbance observers (e.g. The process and measurement noises were considered to be uncorrelated. Iterative Receiver design for Underwater Communication using MIMO-OFDM, Channel estimation and Efficient Modulation schemes, Computing the Least Quartile Difference Estimator in the Plane. In position control, estimated value is compared with the reference position and when both coincide, the motor is held at a particular position for specified time and brought back to original position. High performance robot control systems also call for velocity and acceleration information from the joints. On the other hand, the applications of induction motors (IM) are mainly concerned with motion transmission systems.

As it can be seen in Fig. Once the disturbance affecting the nonlinear system becomes known it can be compensated through the introduction of an additional control term in the loop. These sigma points are propagated through the true nonlinear system, thus generating the posterior sigma-point set, and the posterior statistics are calculated. (30) and Eq. In the outer loop, control of the magnetic flux is performed enabling decoupling between the motor's speed dynamics and the flux dynamics. (38) and Eq. (iii) to overcome certain limitations of the EKF (such as the need to compute Jacobian matrices and the cumulative linearization errors due to approximative linearization of the motor dynamics), Sigma Point Kalman Filters (SPKF), and particularly the Unscented Kalman Filter (UKF) can be used. (, Dannehl & Fuchs 2006] Dannehl, J., Fuchs, F.W. The extended Kalman filter is employed to identify the speed of an induction motor and rotor flux based on the measured quantities such as stator currents and DC link voltage. One important use of generating non-observable states is for estimating velocity. However, to reduce equipment cost and to simplify installation and maintenance, tachometers and accelerometers are not always used in the robotic control loops. The 1×2 Jacobian Jγ(x) is. On this basis, a block diagram model of the dynamic system is presented and an experimental test has been carried out for identifying the system parameters accordingly. Indeed it holds. The second is an embedded MATLAB(R) block implementation.

Flatness-based control of the induction motor with the use of Extended Kalman Filtering in case of tracking a constant setpoint (a) stator's current isd (b) stator's current isq, The approach on flatness-based control of the induction motor that was presented in Section 4 needs knowledge of the electric motor's state vector x=[θ,ω,ψsd,isd,isq,ρ]. Thus the linearized version of the plant is obtained: Now, the Extended Kalman Filter (EKF) recursion is as follows: First the time update is considered: by x^(k) the estimation of the state vector at instant k is denoted. rotation speed and magnetic flux) are not directly measurable (due to sensors cost and limited reliability, sensors failures and difficulties in sensors installation) the significance of state estimation through Kalman Filtering becomes clear. Rank regression in combination with a rank histogram filter in observation space produces better analyses than standard regression for cases with nonlinear forward operators and relatively large analysis error.

With the field-oriented method, the induction motor dynamics is rather similar to that of a separately excited DC motor (Wai and Chang 2001), (Nounou Rehman 2007), (Wai Chang 2004). AC motor circuit, with the a−b stator reference frame and the d−q rotor reference frame, The classical method for induction motors control is based on a transformation of the stator's currents (isα and isb) and of the magnetic fluxes of the rotor (ψrα and ψrb) to the reference frame d−q which rotates together with the rotor (Fig. (17) one obtains. If ψrd→ψrdref, i.e. The state vector of the motor is defined as x=[θ,ω,ψrα,ψrb,isα,isb] and the dynamic model of the induction motor is written as (Horng 1999): J is the rotor's inertia, and TL is the external load torque. It can be observed that, although using a reduced number of sensors, the proposed state estimation-based control scheme for the induction motor provides accurate tracking of the reference setpoints. It has great maneuverability through. of the rotation speed ω, of the magnetic flux ψrd and of the angle ρ between the flux vectors ψra and ψrb.
