| 摘 要： | 感应电机转子电阻的在线辨识和补偿是提高矢量控制系统性能的重要手段。针对感应电机模型的不确定性和非线性,基于扩展卡尔曼滤波(EKF)技术,设计感应电机转子电阻在线估计器,采用模糊控制理论,设计模糊PI速度控制器,根据系统状态的变化,以模糊控制器的输出对PI控制器参数进行修正,从而改善系统的静、动态性能。Matlab仿真结果证明了所设计的EKF转子电阻辨识器和模糊PI控制器的有效性。

| Abstract: | To improve the performance of induction motor vector control system,rotor resistance estimation and compensation on line are very important.Extended Kalman filter(EKF) technology is proposed to estimate motor resistance on line,against model uncertainty and nonlinearity of the induction motor.To further improve the static and dynamic system performance,a fuzzy PI speed controller based on fuzzy control theory is designed,in which the outputs of fuzzy controller revise parameters of PI controller according t... |
