本文提出了改善位移控制电液伺服系统特性的方法,并应用于模拟地震的振动台控制中,取得了满意的结果。在基本的位移控制环路中引进加速度反馈可以改善系统的稳定性,引进速度反馈可以扩展使用频率范围。此方法可以在类似的控制系统中应用。
In this paper, a method to improve the characteristics of displacement control electro-hydraulic servo system is put forward and applied in the simulation of shaking table of the earthquake. Satisfactory results have been obtained. The introduction of acceleration feedback in the basic displacement control loop can improve the stability of the system. The introduction of speed feedback can expand the operating frequency range. This method can be applied in similar control systems.
