A control system for a hydraulic transformer providing hydraulic pressure to a fluid actuator has a hydraulic system for providing a variable pressure input to the hydraulic transformer, and a controller connected to the hydraulic transformer and the hydraulic system for matching the flow demand from the hydraulic transformer to the flow produced by the hydraulic system.

Control system for a hydraulic transformer having variable pressure input

A control system for a hydraulic transformer has a hydraulic system for providing hydraulic pressure to the hydraulic transformer, a controller connected to the hydraulic transformer, the controller for determining the input pressure provided to the hydraulic transformer and for controlling the operation of the hydraulic transformer based upon input pressure provided to the hydraulic transformer.

Control system for a hydraulic transformer

The present invention provides a method and apparatus for controlling a electro-hydraulic system of an earthmoving machine. The electro-hydraulic system may include a pump providing fluid to at least one fluid system. The electro-hydraulic system also includes an engine connected to the pump, and a controller for providing a commands to the engine. The method includes the steps of determining a desired characteristic of the fluid system, comparing the desired characteristic with a deliverable characteristic of the fluid system, and generating a power boost in response to the comparison; thereby controlling the electro-hydraulic system.
