摘要：For the issue of synchronous driving of dual electro-hydraulic servo system, a novel synchronous control method via internal force adjustment based on robust integral of the sign of the error (RISE) is proposed. The nonlinear mathematical model of electro-hydraulic servo system considering unmodeled disturbance is established. The synchronous motion error of dual electro-hydraulic servo system is regarded as the cause of the internal force. In order to eliminate synchronous motion error, the internal force adjustment controller is designed based on the RISE method and further it is integrated with the original PID controller of the system. Based on Lyapunov analysis, it is proved that the internal force can be asymptotically adjusted to zero theoretically. Comparative tracking verification under two position command working conditions is carried out and the simulation results show that the proposed control strategy can improve the synchronous accuracy.
