Abstract
The present study deals with an energy-saving speed-control system which consists of a variable displacement axial piston motor receiving constant pressure oil and a digital servomechanism using two high-speed two-way on/off solenoid valves for adjusting the displacement of the motor. In this system, the motor speed is controlled by displacement adjustment. A command pulse, whose width is determined according to a PD algorithm, is sent to either solenoid valve. It is shown that although the swash plate of the motor is moved stepwise by the on/off action of the solenoid valves, the motor speed can be controlled smoothly because of a low-pass-filter characteristic of the motor and inertia load. This speed control system using a digital servomechanism has very good steady and dynamic characteristics in a wide speed range.
