The application of predictive control in the adaptive control of the pump-motor electro-hydraulic servo system is realized, and under the conditions of time-varying load, the system is experimentally studied.Combining the predictive control and the model reference algorithm in the real-time control , A new method of model reference predictive control is proposed.The step response test and the tracking test under time-varying load show that the proposed algorithm achieves satisfactory results both in control precision and control robustness.
