Abstract

Content: When the speed of actuator is quickly changed in hydraulic system, the great pressure surge and noise are generally caused. In this paper, the optimal control for the minimum pressure surge in shortest speed conversion time is approached. The optimal control is obtained by applying the Pontryagin's Maximum Principle. Experimental results and simulation calculation show that using the optimal control can reduce the pressure surge to about 5 times in comparison with that of step input.
