摘　　要：根据对直流伺服系统的要求及其被控对象的参数时变性 ,提出了一种变趋近律滑模变结构控制设计方法 ,设计了直流伺服变结构控制器。理论分析及仿真研究结果表明 ,该变结构控制器能使系统具有良好的鲁棒性和快速性 。According to the requirement of DC servo system and its parameters variability,a way of sliding mode variable structure control with variable rate reaching law is presented.The DC servo variable structure controller is designed.The theoretical analysis and simulation results show that the system with this controller has good robustness and fine rapidity,and the chattering on the slide module is apparently decreased.
