An Improved Model-Free Adaptive Iterative Learning Control Method

An improved model-free adaptive iterative learning control (IMFAILC) method is proposed for repeating unknown systems using dynamic linearization (DL) through the iteration direction. Based on MFAILC, a time-varying proportional control item is added. Compared with the original MFAILC method, IMFAILC is more general and has better control effect. The convergence and stability of IMFAILC scheme are proved strictly, and the effectiveness of the IMFAILC scheme is confirmed by simulation.
