English Description:
Aiming at the problem that it is difficult to obtain the optimal values of Kalman filter system noise matrix and measurement noise matrix in induction motor speed estimation based on extended Kalman filter (EKF), a speed estimation method based on Improved Particle Swarm Optimization (PSO) is proposed. By combining the advantages of genetic algorithm and particle swarm optimization algorithm, the particle swarm optimization algorithm is improved by using an adjustable algorithm model. The improved particle swarm optimization algorithm is used to optimize the system noise matrix and measurement noise matrix in the extended Kalman filter, and the optimized Kalman filter is applied to the speed estimation of induction motor.
