DESIGN OF ROBUST CONTROLLER IN ELECTROHYDRAULIC LOAD SIMULATOR
Application of μ theory in the electrohydraulic load simulator is studied. Robust control strategy of the electrohydraulic load simulator is put forward. The electrohydraulic load simulator is a complicated mechanical-electronic-hydraulic compound system, moreover it is a strong coupling and time-varying controlled object.Synthetically considering uncertainties such as parameter perturbations, model perturbations and external disturbances etc., robust force controller of the electrohydraulic load simulator is designed using μ synthesis theory. Robust stability and robust performance are analyzed by μ values of the system in which robust force controller is used. Moreover,experiment results of systems using robust force controller and classical force controllers are shown. The results indicate that the designed robust force controller is efficiency and superiority.
