Direct Drive Volume Control of Electro-hydraulic Servo System and Its Application to the Steering System of Ship

Direct Drive Volume Control (DDVC) of electro-hydraulic servo system has synthesized the advantages of high power of hydraulic system and flexible control of the motor. It also has other features such as energy saving, high efficiency, small bulk and high reliability. Therefore it is widely consid- ered to be one of the most important developing directions of the hydraulic control system. The construction and the characteristics of DDVC of electro-hydraulic servo system are presented. On the background for application to the ship steering system, DDVC of electro-hydraulic servo system for the control actuator of ship is designed and the model machine for experiment is manufactured. Theoretical analysis and experimental research show that DDVC, used as the power equipment of the control actuator of ship, can meet the needs for performance. Contrasted with traditional drive equipment of the control actuator ship, DDVC has advantages of energy saving, higher efficiency, higher reliability, simpler construction, easier control and smaller bulk. From the foregoing reasons, we can make a conclusion that DDVC will be a extensive prospective power equipment of the control actuator of ship in future.
