| 摘 要： | 为提高交流永磁同步电机伺服系统的控制精度,提出了一种基于比例切换控制策略的滑模变结构控制方法.先给出伺服系统模型,再设计滑模控制器,通过选取合适的滑模面得到系统比例切换控制输入.分别讨论了被控对象为时不变和时变情况下的系统响应情况,并与PI控制进行对比,以分析本文方法的优劣.仿真结果表明,所设计方法控制精度高,且具有较好的鲁棒性和快速性.

| Abstract: | In order to improve the control accuracy of servo system of AC permanent magnet synchronous motor (PMSM), a sliding mode variable structure control method based on proportional switching control strategy was proposed. Firstly, the servo system model was given. Then, the sliding mode controller was designed, and the proportional switching control input was obtained by selecting the appropriate sliding mode surface. The responses of time-invariant and time-varying systems were discussed separately, and the response was compared with that of PI control to analyze the advantages and disadvantages of the method. The research results showed that the designed method had high control accuracy, good robustness and rapidity. |
