Abstract

This paper is concerned with the design of iterative learning controller combined with a PID feedback loop for controlling electro-hydraulic position servo systems based on a deterministic approach. The system is treated as an uncertain system with bounded uncertainties where the bounds are assumed known. The simulation results show that the effectiveness of the method to the system is better in spite of the uncertainties and nonlinearities present in the system.
