为了提高感应电机控制系统的鲁棒性和响应能力,提出了一种基于全局模糊指数趋近律滑模的感应电机控制方法,研究了在感应电机矢量控制系统中,针对滑模控制中控制量的求取需整定多个参数带来的复杂性问题,以及传统滑模变结构控制中到达模态不具有鲁棒性的缺点,结合趋近律法设计了一种基于全局模糊指数趋近律的滑模控制方法,分析了控制器的设计方法,并对所设计的系统进行了仿真分析和实验研究。仿真和实验结果表明,基于全局模糊指数趋近律的滑模控制方法具有良好的动态性能且动态过程中有较小的超调,并且系统对于负载扰动具有较强的鲁棒性。

In order to improve the robustness of the induction motor control system and the speed of system response, the induction motor control method based on the globe fuzzy SMC （sliding model control）was proposed. The induction motor control system based on vector control technology was researched. We should give the range of the coefficient when confirm the controller in sliding model control and the traditional approach of sliding mode control mode does not have the robustness of the shortcomings. Based on the problems a globe index reaching law SMC combined with reaching law control was proposed, and the process of controller＇s design was analyzed. Simulation and experiment research on the control system were carried out respectively. The results demonstrate that the system have a smaller overshoot and a better rapidity of dynamic response, and have strong robustness to load disturbance.
