On the Design and Analysis of a Learning Control Algorithm for Point-to-point Tracking Tasks

A simple iterative learning control approach is proposed to track specific target points in this work. For a general linear system, a P-type point-to-point ILC and a PD-type point-to-point ILC laws are designed, respectively. The two control laws only use the tracking error at the specified point to update the input signal at the corresponding specified point. The input signal between two consecutive specified points remains the same as the input signal at the previous specified point. The proposed method has the advantages of simple structure and easy application. The convergence analysis and simulation results further confirmed the availability of the method.
