A Quantitative Feedback Control System Design for the Multi-axis Simulator having Uncertain Plants
This paper presents design of the quantitative feedback control system of three axes hydraulic road simulator with respect to the dummy wheel for uncertain multiple input-output(MIMO) feedback systems.The simulator consists of the electronic servo valve,hydraulic pressure pump,hydraulic actuators and control equipments.This simulator has the uncertain parameters such as fluid compressibility,fluid leakage,electrical servo components and nonlinear mechanical connections.This work has reproduced the random input signal to implement the real road vibration’s data in the lab.The replaced m2 MISO equivalent control systems satisfied the design specifications of the original m ⅹm MIMO control system and the mathematical method using quantitative feedback theory based on schauder’s fixed point theorem is developed.This control system illustrates a tracking performance of the closed-loop controller with low order transfer function G(s) and pre-filter F(s) having the minimum bandwidth for parameters of uncertain plant.The efficacy of the designed controller is verified through the dynamic simulation with combined hydraulic model and Adams simulator model.The Matlab simulation results to connect with Adams simulator model show that the proposed control technique works well under uncertain hydraulic plant system.The designed control system has satisfied robust performance with stability bounds,tracking bounds and disturbance.
