摘　　要：目的探讨系统非最小实现对在电液速度伺服控制系统的动态特性的补偿作用.方法分析电液速度伺服控制系统阻尼的构成,变化原因及对系统动态特性的影响;构造电液速度伺服控制系统一种非最小实现方式,利用此种非最小实现仅使用积分器产生对输出信号的一次微分对系统的阻尼进行补偿,进而改善电液速度伺服控制系统的阻尼和动态特性;模拟仿真系统非最小实现方法对在电液速度伺服控制系统的动态特性的补偿作用和效果.结果系统非最小实现方法对在电液速度伺服控制系统的阻尼补偿作用显著,动态特性得到改善,效果明显.且在阻尼在较大的范围内变化时仍然有补偿作用.结论模拟仿真表明此方法可以使电液速度伺服控制系统的阻尼得到显著改善,系统动态特性显著提高.In this paper the dynamic feature compensating of the electro-hydraulic velocity servo system is analyzed by a non-least realization system. The constructive feature of the system damp and its affect to the dynamic feature are worked out. Through the non-least realization, the integrator provides a differential for the output signal to compensate the damp, so as to improve the damp and dynamic feature of the electro-hy- draulic servo system. The research simulates the dynamic feature and compensating effects of the electro-hy- draulic servo system using the non-least realization. The frame of the compensate system is worked out and its parameter configuration is analyzed. The simulation results show that the non-least realization of the sys- tem can compensate the damp of the system when the damp changes in a large range and the responding fea- ture of the compensate system is better.
