Abstract: This paper deals with the combined dynamic optimal and parameter adaptive control of the electrohydraulic servo systems. An optimal adaptive controller, which needs teas computation and is suitable for the on-line operation, is proposed in the paper on the basis of the optimization theory. Effectiveness and availability of the controller is verified by the simulation and experiment of an electrohydraulic position servo system.
