Missile PID controller parameter tuning based on iterative learning control

On the basis of sufficient analysis to the characteristic of iterative learning control and PID controller parameter tuning, an idea of applying iterative learning control to PID controller parameter tuning was aroused in this paper, we choose the linear model around the character point of Missile Roll Attitude controller as the research plant, transforming the problem of PID controller parameter tuning into the problem of open-close loop iterative learning control problem. The stability of PID controller parameter iterative learning control system and the astringency of controller parameters were verified for the first time through the construct of a compress mapping arithmetic operator, and a novel stop condition design scheme of integral type is advanced at the same time, the iterative learning of PID controller parameter was then successfully solved. The ultimate simulation study validates the correctness and the effectiveness of the theory.
