摘　　要：为了克服感应电动机逆系统抗扰动能力弱的缺点,结合滑模变结构原理设计了一种指数趋近律的滑模变结构逆解耦速度控制器,并对该控制策略的可行性进行分析。仿真结果表明,笔者提出的控制策略提高了感应电动机的鲁棒性,具有响应速度快、超调量小等优点,验证了滑模变结构感应电动机逆解耦控制策略的有效性。To overcome the shortcomings of poor anti-jamming ability of the inverse system of the induction motor, inverse decoupling speed controller with exponential reaching law was designed based on the inverse system in combination with the theory of sliding mode variable structure. In addition, the feasibility of the control strategy was analyzed. Simulation results indicated that the control strategy increased the robustness of the induction motor with rapid response speed and little overshoot. It also verified the effectiveness of the inverse decoupling control strategy for the induction motor based on sliding mode variable structure.
