The method of slide-mode variable structure control is such a strategy that is characterized of low mathematical model precision, insensitiveness to system parameter variation and external disturbances, omission of parameter identifications, fast dynamic response and easy implementation. These advantages make it suitable to high performance vector controlled AC motor drives.
滑模变结构控制是一种强鲁棒性的控制方法,对系统数学模型精度要求不高,具有快速响应、对参数及外部扰动变化不敏感、无需系统在线辨识,实现简单而且很适合计算机实现等优点,因此,很适合高性能的交流电机矢量控制系统。
