摘　　要：提出了一种内置式永磁同步电机(IPMSM)无抖振非线性滑模控制新方法。分析了IPMSM非线性输入输出解耦技术;考虑了模型不确定性的上限边界,然后设计了一种新型无抖振滑模变结构控制器;最后,在基于数字信号处理器(DSP)TMS320F2812的IPMSM实验平台上的实验结果表明,系统有效减小了抖振现象,获得了满意的动、稳态和抗干扰性能。This paper proposes a new method of chattering-free non-linear sliding-mode controller for interior permanent magnet synchronous motor（IPMSM）.The input-output feedback linearisation technique is used to derive a linearisation model.The upper bounds of the modelling uncertainties are considered,and then a new non-linear slidingmode control algorithm is proposed to obtain a chattering-free controller.Finally,A digital signal processor（DSP）,TMS320F2812,is used to realize the proposed control system.The experimental results show that the proposed system can effectively reduce the chattering phenomenon and achieve satisfactory performance,including fast transient responses,good load disturbance rejection responses and good tracking responses.
