DEVELOPMENT OF FUEL PUMP-MOTOR ROTATIONAL SPEED CONTROL SYSTEM

In this paper a discussion is made of the importance of the dynamic experimental stand of a power device control system,and the importance of the semi-physi-cal simulating test.Stress has been laid 011 the development of electro-hydraulic servo fuel pumpmotor rotational speed control system, including design method, static and dynamic calculation, mathematic modeling, time and frequency domain analysis, correctionand experiment result analysis.The fuel, pump-motor rotational speed control system has rapid dynamic response,easy operation,smooth control, good static accuracy and so on.It also has larger power,higher speed, double-pump-control fuel motor and reasonable energy consumption,and thus has wide application.Successful development of the system.Not only provides the equipment for semiphysical simulating test of aviation "power device control system but also the dynamic test stand for highquality ground rotational speed control system.
