摘要
对一不稳定的液压转台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, 仿真结果表明该方法显著改善系统的性能, 使系统具有较强的鲁棒性和控制品质, 是一种有效的控制方法。
The state feedback control was used for a nonstable hydraulic swivel servo system.In order to improve the robustness of the system,a servo-compensator was designed with internal model principle.Then poles of closed-loop were rationally selected and a expected closed-loop state equation was obtained to correct state controller and state observer.Compared with the method of PID control, the simulation results show the method is quite effective and the system performance is improved greatly so that it has higher robustness and better characteristic.
