电液比例位置同步控制系统的控制结构研究

CAD Investigation into control structure of electrohydraulic proportional position synchronized control system

本文着重分析了电液比例位置同步控制系统的结构对稳态和动态同步误差的影响，并进行了相应的仿真和实验研究。研究结果表明，并联结构加同步误差反馈并辅之以比例控制的特殊处理算法的比例位置同步控制系统，可具有二阶无静差度和很好的同步控制特性。

This paper emphatically analyzes the effect of the structure of electrohydraulic proportional position synchronised control system on stable and dynamic synchronized errors, and carries out respective simulation and experimental study. The test results show that the proportronal positoon synchronized control system with speclal disposal algorithm of parallel connection structure, synchronized error feedback to gether with proportional control has no static error to second order and very good synchronized control characteristics.
