摘要
将扩展卡尔曼滤波(EKF)应用于永磁同步电机(PMSM)调速控制,利用Matlab/Simulink搭建P M S M矢量控制系统仿真模型。仿真结果表明,控制系统在高、低速以及带负载情况下都能平稳运行,EKF估计得到的转角θ和转速ω能很好的跟踪实际的转角与转速。
Extended kalman filter （EKF） was applied into permanent magnet synchronous motor speed control while Matlab/Simulink was employed to establish the simulation model of the vector control system of PMSM. The simulation result showed the control system working smoothly under both high and low speed, as well as with load or without load. The rotating angle θ and speed ω resulted from the EKF estimation had excellent ability to track the actual angle and speed.
