Automation of a Hybrid Control for Electrohydraulic Servo-Actuators with Residual Dynamics

In this paper, a hybrid position/force controller for electrohydraulic servo-actuators is designed in the presence of residual dynamics. The purpose to apply cycle movement that mostly used industrial fatigue test applications, which consists imposing specified force on flexible load after some position. This can be repeated several times with different magnitudes and frequencies position trajectories. Some damages could occur at switching times, especially To avoid any trajectory generator designed. Then, our contribution defines method automatically generate signal order commute between two controllers abrupt change state. show effectiveness proposed approach, simulation tests are carried out system.
