For precise tracking control of a class of nonlinear systems with unknown parameters over a finite time interval, an open-closed-loop PI-type iterative learning control scheme is proposed. Sufficient and necessary conditions for the convergence of the proposed learning scheme are given. The conditions are more general than the known results.
