Abstract
Electronic control for a hydraulic system driving an auxiliary power source is provided, with specific application as a system for controlling the operation of a hydraulically driven AC generator. The system may includes a hydraulic pump, a hydraulic motor drivably connected to the generator, a fluid circuit for circulating fluid from the pump to the motor and back. The fluid circuit may contain a bypass conduit to bypass the motor. The system also includes a proportional servo control valve assembly for controlling the fluid circuits and a control circuit for controlling the proportional control valve assembly. The control system can be capable of controlling the flow of hydraulic fluid to the motor powering the electrical or mechanical system. Sensors for measuring the operating parameters of the system and an operator interface module can influence the operation of the system.
