An integral sliding mode based control scheme was put forward by aimed at the problem of load pressure force control of diecushion cylinder of hydraulic press. This method was fully exploited the merit of robustness of sliding mode control, which implemented tracking control of desired load pressure trajectory of diecushion cylinder precisely, in addition, it had good disturbance rejection function to uncertainties and external disturbances of the parameter. Theoretical analysis and simulation results in comparing show the effectivenessof the proposed control algorithm.
