Abstract: A design method of adaptive sliding mode control law based
on the equivalent control is presented aiming at the tracking control
problem of electrohydraulic servo force control systems with
uncertainties and nonlinearities. To eliminate the influence of
uncertainties on the control performance a parameter adaptive method is
used. Consequently the goal of robust tracking control is obtained. To
illustrate the feasibility of this controller, it is implemented using a
microcomputer on an electrohydraulic servo system of fatigue testing
machine. The results of the real-time control verify the validity of the
proposed adaptive sliding mode control method.
Key words: Electrohydraulic servo force control systems Adaptive
