APPLICATION OF ITERATIVE PID CONTROLLER IN HYDRAULIC SYSTEM

Abstract

Abstract: Because the working process of high speed hydraulic press is repeat and large quantity of heat produced by the hydraulic system throttling, a new iterative PID controller is designed. By using the memory ability of computer, the controller keeps the last times’ error information and then applies this information to the next times’ control. The simulation and practice application shows the iterative PID controller has the characteristics of simplicity and high repeating precision, which can meet the need of high speed hydraulic press.

Key words: Hydraulic system, Iterative learning, PID controller
