摘　　要：针对传统感应电机无速度传感器控制系统中参数变化和负载扰动对系统运行性能的影响,该文将滑模控制与自适应滑模观测器相结合,构成了感应电机无速度传感器的双滑模控制系统,并建立了该系统的SIMULINK仿真模型。系统仿真结果证实了在电机参数变化和负载扰动时,该系统具有无超调、鲁棒性强、动态响应快等优点。Combined an induction motor speed sensorless bi-sliding mode control system with adaptive sliding mode observer and sliding mode control to solve the influence of operation performance in common induction motor sensorless control system caused by variation of parameter and external load disturbance, built an system simulation model. System simulation experiments prove that the sliding mode control system with adaptive sliding mode observer has properties of better robustness, no overshoot and quick dynamic response when variation of parameter and external load disturbance happen.
