A closed-loop D-type iterative learning control law for discrete linear uncertain systems and its application to electrohydraulic servo systems

In this paper, a closed-loop D-type iterative learning control scheme for the precise tracking control of a class of discrete linear uncertainty systems is presented. The conditions, which guarantee the convergence of the scheme, are given and then proved. Subsequently, this paper described the application of this scheme in the field of electrohydraulic servo systems. Simulations show that the good result has been obtained using this scheme.
