Abstract
A hydraulic generator drive system. The drive system has a control system that utilizes a first loop control that receives a signal associated with hydraulic pump or motor output and sends a command signal to a pump controller in order to control the hydraulic pump. Simultaneously, the control system has a second loop control that receives an input signal from the generator and sends a command signal to an armature to actuate the generator. As a result, a single control system is provided to control the speed and voltage output of the generator.
