摘　　要：针对感应电机矢量调速系统中存在的受速度传感器限制以及系统动静态性能受参数变化和外加扰动影响大等问题,设计了一套无速度传感器感应电机动态滑模调速系统。在d-q同步旋转坐标系下,首先基于扩展卡尔曼滤波器对感应电机转子转速进行估算,在此基础上,利用动态滑模控制来实现转速的闭环调节。仿真结果验证了该系统的有效性。A sensorless dynamic sliding mode speed regulation system of induction motor was proposed, in or- der to solve the problem of speed sensor limitation and bad influence to dynamic and static performance brought by motor parameters variations and uncertain disturbances. In the dq synchronous rotating coordinate, the rotor speed was estimated based on extended Kalman filter, then the dynamic sliding mode theory was used to realize the closed-loop speed regulation. Simulation results validated the high performance of the control scheme.
