【Abstract】 A sampled-data iterative learning controller is proposed for a class of nonlinear continuous-time systems with time-delay. The learning algorithm is constructed without any differentiation of the output error, and given a sufficient condition for convergence. Without initial error and disturbances, zero error between the plant output and the desired output can be shown at each sampling instant. If initial errors or disturbances exist, output error is uniform bounded. Simulation results demonstrate the effectiveness of the proposed algorithm.更多还原
