Abstract
A concise position and average velocity closed-loop control method based on PID ofvalve controlled hydraulic systems is proposed for both positional precise control and averagevelocity precise control. First, set the target position and the target average velocity; secondly,the average velocity closed-loop control is preferentially carried out at start-up; thirdly, switchto the position closed-loop control circuit when the ratio of the actual position to the targetposition reaches a critical value; at last, adjust the PID parameters to a proper configuration.The simulations show that this method can acquire both the position and the average velocitycontrol with sufficient accuracy at the same time, in which the position deviation can be lessthan 0.001% and the average velocity deviation is 2.08%. In addition, the simulations indicatethat the system can maintain almost the same precision of the position control and the averagevelocity control by adding an external load as a disturbance item.
