This paper presents a position control of a single rod electro-hydraulic actuator based on an integrator backstepping approach and tuned controller gain parameters by using a Particle Swarm Optimization (PSO). The aim of this paper is to develop optimal Back Stepping Controller (BSC) architecture on a nonlinear Electro Hydraulic Servo System (EHSS) of asymmetric cylinder to improve the position control performance. The influences of getting the parameters on the control law are analyzed in order to establish some rules of optimization. This can be determined automatically and intelligently by minimizing Integral Square Error (ISE). The proposed controller is simulated and then implemented to the experimental test bed to track the desired signal and test the limits of its performance. The simulation and experimental results are given to demonstrate the effectiveness of the proposed controller.
