ABSTRACT:
Apparatus and method for controlling at least one hydraulic actuator by the hydraulic fluid discharged by a variable displacement hydraulic pump through a closed-center valve and a separate bypass valve. The apparatus receives a mode signal and a stroke signal and responsively controls the output of the variable flow hydraulic pump with either velocity or force modulation control.
