| Abstract: | In this paper, a frequency-domain design method of an iterative learning controller for a class of plant G(s) is proposed, and an iterative learning controller is designed. The sufficient conditions for the convergence of the iterative learning algorithm in an arbitrary initial state are given. it is proved that the output signal converges and remains in the neighborhood of the desired signal after iteration, the errors which do not depend on the iterative initial state are uniformly bounded, and iterative initial state is independent of desired state and desired input. The role of feedback controller is also discussed. Simulation results are presented to demonstrate the effectiveness of the proposed iterative learning control. |
