摘 要:This paper presents the one-axis hydraulic road simulator control technology for reproducing the random input signal to implement the real road *** simulator consists of the hydraulic pump,servo valve,hydraulic actuator and its control *** force control system using QFT is utilized to control the simulator effectively and illustrates a tracking performance of the closed-loop controller with low order transfer function Gi(s) and pre-filter F(s) for a parametric uncertain plant.A force controller is designed to communicate the control signal between simulator and digital *** specification is satisfied with upper and lower bound tolerances on the steep response of the system to the reference *** efficacy of the QFT force controller is verified through the numerical simulation,in which combined dynamics and actuation of the hydraulic servo system are *** simulation results show that the proposed control technique works well under uncertain hydraulic plant *** Labview software is used to make up for the real controller in the real-time basis,and the experimental works show that the proposed algorithm works well for the one-axis Hydraulic road simulator.
