Abstract

In this paper the problem of experimental control of hydraulic actuators is considered. To deal with mechanical and hydraulic uncertainties two different controllers are synthesized: a backstepping controller and a LQR-2DOF controller. Experimental results of both implementations are analyzed in the context of practical difficulties, mainly the measurement of acceleration. These results illustrate the main features of these controllers when applied on a hydraulic actuator.
