摘　　要：控制系统的性质主要由系统的极点决定,要使电液力伺服系统的动态性能满足设计要求且达到最佳,则系统要有优良的极点。将电液力伺服系统转变为状态方程结构形式、利用分析及仿真得到系统的最佳极点,求出系统极点配制的反馈矩阵、从而对系统的极点实现了最佳极点配置。仿真结果表明,电液力伺服系统实现了最佳极点配置后,系统的动态性能明显提高。The character is mainly decided by the top configuration of the control system. The system has to have the optimal top configuration if the dynamic performance of electrical-liquid force servo system is contented with the design demand. The electrical-liquid force servo system is changed into the structure of the state space. The top configuration is obtained by analyzing and imitating. The feedback matrix of the top configuration is also obtained, so the top configuration is carried out. The result of imitation indicates that the dynamic performance is improved obviously after the optimal top configuration is realized by the electrical-liquid force and servo system.
