Iterative learning control for 2-D systems

In this paper, the application of iterative learning control (ILC) in two-dimensional systems is considered and a method of ILC for 2-D systems is introduced so that the output of the process follows a desired trajectory. In this method the input of process in each iteration is determined by an innovative method called two-dimensional method by means of the obtained error between the output of the process and the desired trajectory which was given in previous iteration and the ability of this new method is illustrated by computerized simulation and the obtained results are compared with the results of one-dimensional method which was adapted to a 2-D one. Also the convergence of these methods is considered.
