Abstract: According to the time-varying characteristic of hydraulic servo system,the model of po-sition synchronization system for dual electro-hydraulic servo motor was established.Based on fuzzy control er,a complex cross-coupling control method was put forward to compensate the synchronization error caused by time-varying characteristic and external interference.Simulation results showed that the method could improve the precision of position synchronization.
