Abstract

Abstract:

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.

Key words: electrohydraulic , load , simulator, , &mu, , synthesis, , &mu, , analysis, , robust, , uncertainty
