摘要

This paper presents a robust compound control for Hydraulic Flight Motion Simulator servo system, which suffers from highly nonlinear dynamics, large parameter variations and severe load coupling among channels.The proposed control consists of a robust inner-loop compensator for rejecting perturbation and disturbance, an outer-loop controller for guaranteeing overall performance of closed-loop system and a command signal feedforward compensator for compensating time lag of dynamic system.To verify the validity of the proposed control strategy, simulations and experiments are made.The results show that the controlled system is highly robust against the large parameter and load variations and the controller possesses excellent capability of suppressing the severe load coupling among channels and improving the trajectories tracking performance.
