Abstract :
Aimed at the external disturbing force of a hydraulic servo system, the paper designs a feed-forward disturbance compensator Based on the principle of structure fixity. A control law is designed by applying the augmented linear quadratic regulator (ALQR), which makes the hydraulic servo system follow the ideal position signal quickly and well. Eventually, the simulation result shows that this method possesses the good performance.
