For the trajectory tracking control of linear time-variant system, an iterative learning control method is presented and the convergence proof is given. This method does not need detailed knowledge of the system. However, a reference batch is designed, in which some small change of input trajectory in the current batch is applied to the system. Then its output trajectory is obtained. The ratio of the input change and corresponding output change in the current and reference batch is used as the gain in the learning law for calculating the input of next batch. Thus the method can track the desired trajectory successfully while the batch is running on. The simulation results show the effectiveness of the method.
