【Abstract】 A new adaptive control scheme is proposed. The adaptation law designed only for the block with time-variant parameters in electrohydraulic position servo systems can not only aviod the inverse stability of adaptive control, but also be implemented easily by a microprocessor within a short sample period. So this method suits particularly the systems with high dynamic response as same as electrohydraulic position servo systems. The simulation result indicates that it has a evident effect for restraining the influence of time-variant parameters, and can obtain a good control effect.更多还原
