Research on the Simulation of a Iterative Learning Control Strategy of the Electrohydraulic Servo Force Control System of a Artificial Hip Joint Simulator

The paper first gives a introduction to the electrohydrolic servo force control system of a artificial hip joint simulator, and analyses the static characteristics of the force system. The paper proposes a proportinal closed loop one-order input-leading iterative learning control algorithm, and gives the simulation results of control effect. The research results show that using iterative learning control algorithm can improve the tracing accurate of the force system.
