In this paper, an idea of applying iterative learning control to PID controller parameter tuning was proposed on the basis of sufficient analysis to the characteristic of iterative learning control and PID controller parameter tuning. We choose the linear model around the character point of roll tunnel as the research plant, transforming the problem of PID controller parameter tuning into the problem of open-close loop iterative learning control problem. Making use of Laplace transformation, the stability of PID controller parameter iterative learning control system and the astringency of controller parameters were verified through the construct of a compress mapping arithmetic operator. A stop condition design scheme of integral type is also advanced at the end of this paper, and the iterative learning of PID controller parameter was then successfully solved. The ultimate simulation study validates the correctness and effectiveness of proposed scheme.
