N2 - The hydraulic motor is usually controlled by the servo valve, with the speed encoder composing a closed loop system. While considering the power efficiency, the secondary control which changes the displacement of the motor is always a direct method, though the response time may be a bit longer. For the purpose of accuracy and efficiency, a control method of both valve control and secondary regulation is proposed in this paper. Compared with the traditional valve-controlled motor system, the throttling loss of the servo valve can be reduced. The simulation using AMESim is carried out to verify the effectiveness and feasibility of the principle.
