在结构抗震试验室的平台上,针对电液伺服加载系统模型参数——位置具有时变性和易受外界干扰的特征,将模糊控制与PID控制结合,提出了一种多模态(P-Fuzzy自适应PID-PI)分段控制策略.该控制方法利用P控制的快速响应特性,Fuzzy自适应PID对系统模型参数具有自适应调整的特性,以及PI控制对系统稳定状态动态偏差的快速调整特性,实现了电液伺服加载系统的位置的稳定调节.通过仿真实验分析得出,实现了良好的控制性能.

Based on the seismic lab platform In this paper,aimed at model parameters of electro-hydraulic servo loading system,position has the characteristic of variability and susceptible to external interference,the combination of fuzzy control and PID control.This paper proposes a multi-modal (P-Fuzzy adaptive PID-PI)control strategy of segmentation.This control method using fast response characteristic of P control,adaptive characteristic of Fuzzy adaptive PID system modal,as wel as steady-state PI control system quickly adjust the characteristics of dynamic variation to achieve the position of electro-hy-draulic servo loading system stability and regulation.
