In order to improve synchronization accuracy,a compound angle-synchronizing control strategy is presented for dual electro-hydraulic motors in hydraulic flight motion simulator.This compound angle-synchronizing controller includes velocity feed-forward synchronizing control scheme and torque decoupling control scheme.This control strategy fully considers the mechanical structure and stiffness of the dual electro-hydraulic motors.The mathematical model of dual electro-hydraulic motors is established.A prototype testbed of dual electro-hydraulic motors has been set up,the compound controller is tested by the experiment.By analyzing experiment results,the designed compound angle-synchronizing controller can restrain torque coupling disturbance and improve the angle synchronization accuracy compared with traditional anglesynchronizing controllers.
