摘要
结合传统PID控制和滑模变结构控制两者的优点,提出了交流伺服系统的PD和滑模变结构的复合控制,使系统有良好的鲁棒性。本文分析了交流电机的数学模型,着重设计了三个闭环系统控制器的设计。仿真实验表明控制器能够提高控制系统的静态、动态性能和鲁棒性。
A novel compound control scheme for AC servo system with PD and sliding mode variable structure control is presented, which integrates advantages of sliding mode variable structure control and traditional PID control. It makes that AC servo system has excellent robust of variable structure control. Mathematical model of AC servo system is deducted, regulator of three closed loop is designed. The simulation and comparison show that regulator can improve the dynamic and static performance and the robustness.
