Abstract

Variable-pressure pump can greatly improve the work efficiency of hydraulic actuator in missile by adaptively adjusting its output pressure and flux. In this study a model reference adaptive control with sliding mode variable structure is proposed, based on the fact that the variable-pressure pump has a large parameter perturbation, large load fluctuation and quick dynamic response. The computer simulation was performed and the simulated results show that the proposed scheme can provide higher dynamic performance and better robustness.
