【Abstract】 The hyper-pressure control system for electric direct driving hydraulic system was introduced. The mathematical model of the system was built,and the performance of this system was analysed. In virtue of simulations of step signal and slope signal response with the algorithm of PID,the property of this system was analysed. The results shows that the system works stably and timely and can improve the control precision of the pressure in a certain extent.更多还原
