针对PMSM（永磁同步电动机）伺服系统滑模变结构控制器设计过程中存在的滑模切换函数到达阶段不具有鲁棒性及控制器输出存在抖振问题,设计了具有全程鲁棒性的参数自适应全局滑模变结构位置控制器。首先设计一个系统动力学特性表现为状态反馈控制系统的滑模面,然后在选定的全局滑模面下,根据到达条件给出控制器的设计方案。对PMSM伺服系统的仿真试验证明,所设计的参数自适应全局滑模变结构位置控制器克服了伺服系统不确定因素带来的影响,实现了具有一定自适应能力的高性能PMSM伺服控制系统。

A parameters adaptive global Sliding Mode Variable Structure （SMVS） position controller with robustness in whole situation is presented for a Permanent Magnet Synchronous Motor （PMSM） servo system specific to the reaching phase of sliding mode switching function doesn＇ t have robustness and the outputs of controller have chattering. First, a sliding surface is given in terms of dynamic per- formance by state feedback control system. Then, the design scheme of controller is provided on the basis of reaching condition under the selected global sliding mode surface. Simulated and experimental results show that the proposed parameters adaptive global SMVS position controller overcomes influence of uncertainty in servo system,it makes the PMSM servo system posses better adaptive ability and high performance.
