一种新型趋近律的滑模控制在永磁同步电动机中的应用

针对永磁同步电机(PMSM)的负载转动惯量较大时,会产生很大的惯性转矩,因而对系统的控制性能产生很大的影响,本研究提出并设计了一种新型趋近律的滑模变结构控制器。这种趋近律结合了指数趋近律和幂次趋近律的优点,仿真结果表明,该控制器设计方法实现简单,对抖振有明显抑制,且具有较快的响应速度。

Research on Application in Permanent Magnet Synchronous Motor Based on A New Reaching Law Sliding Mode Control

When permanent magnet synchronous motor(PMSM) loads of greater moment of inertia,it will have a large inertia torque and a huge impact on the control system performance.In this regard,a new type of sliding mode variable structure reaching law controller was proposed and designed in this paper.The reaching law combines the merits of the index reaching law and the power of reaching law,the chattering problem has been obviously restrained and the controller enables the system to be of good fastness.The simulation results show that the controller design method is simple and the system has a satisfying performance.
