摘要
对伺服系统采用状态反馈控制方式 ,应用内模原理 ,引入伺服补偿器 ,通过合理配置闭环极点 ,确定状态反馈矩阵和观测器矩阵。与常规的PID控制相比较 ,仿真结果表明该系统具有较强的鲁棒性和控制品质 ,可获得比PID控制方法更好的控制效果 ,是一种有效的控制方法。
The state feedback control is used for servo system. In order to improve the robustness of the system, a servo-compensator is also designed with internal model principle. Then poles of closed-loop are rationally selected and a expected closed-loop state equation is obtained to correct state controller and state observer. Compared with the method of PID control, the simulation results show the system has higher robustness and better characteristic and the method is quite effective.
