Extended Kalman filter (EKF) is widely used for speed estimation in sensorless vector control of induction motor. The major and unsolved issue in the practical implementation of the EKF is the choice of the process and measurement noise covariance matrices. In this paper, a speed estimation method using EKF optimized by improved particle swarm optimization(More)
The particle swarm optimization (PSO) algorithm is widely used in identifying Takagi-Sugeno (T-S) fuzzy system models. However, PSO suffers from premature convergence and is easily trapped into local optima, which affects the accuracy of T-S model identification. An immune coevolution particle swarm optimization with multi-strategy (ICPSO-MS) is proposed(More)
Estimation of rotor resistance rapidly and accurately has received a lot of attention due to its significance in improving the performance of induction motor(IM) vector control system. In this paper, algorithm of estimating rotor resistance of IM based on extended Kalman filter(EKF) is presented. The algorithm can estimate the rotor resistance on line by(More)
