| Abstract: | A new method of iterative learning control is Presented for a class of non linear discretetime systems with unknown parameters.In this method,the learning gain terms are determined by iterative estimation of system dynamics and therefore it is avoided to determine the learning gain terms through the objectivity.Proof and conditon are stated for convergence of the proposed method.Simulation study for a robot manipulator has been carried out.The results of simulation show the validity of the puoposed method,its robustness to the initial state error and the estimating error for system dynamics. |
