Abstract

A control system for controlling position of an object includes an integrated actuation package utilizing an electric motor driven servopump (3) to control actuator (4) position. The electric motor (2) operates at a constant direction and speed and has augmented system rotational inertia. Additionally, position of a swashplate (7) on the variable displacement servopump (4) is adjusted directly by an electrically powered rotary actuator (30).
