Abstract: According to characteristic of synchro-compensation eliminating disturbance torque for electro-hydraulic loading simulator, referring to the method of model reference adaptive control system, takes steering as referring model, synchro-motor as controlled system to improve the precision of synchro-compensation and eliminate disturbance torque at most. The results of computer simulation and analysis show that the method is effective.
