Abstract
Disclosure is made of a precision hydraulic energy delivery system that directly couples the pump to a primary mover (motor) and a related motor control. The system provides flow control of a hydraulically driven machine without the use of downstream devices by employing motion control algorithms in the motor control. Control features are electronically integrated into the hydraulic system by using control algorithms and subroutines specifically developed for the prime mover servo control system coupled to the pump.
