electrohydraulic transmission systems, state controller, modeling and simulationAbstract
This paper deals with the synthesis of state controller for an electrohydraulic power transmission system. There are shown the mathematical model of the electrohydraulic system and state controller synthesis method with state space feedbacks. The controller coefficients are obtained from preliminary defined error performance index. The response curves are obtained from computer simulation. The results are given in a few graphics.
