Abstract
Energy efficient and environment conscious solutions are currently in high demand. This paper illustrates the potential of pump-controlled actuators such as directly driven hydraulic drives (DDH) for various zonal hydraulics applications. A novel pump-controlled actuator, powered directly by a servo motor is considered for industrial and mobile applications replacing conventional valve-controlled hydraulics. This solution is targeting improvements in energy efficiency, especially for continuous operation systems, however, due to the nature of the solution, system response has high dependency on electric motor dynamics. Therefore, adaptive controller is designed to realise benefits of the DDH. Study presents results of performance by simulation of this new concept.
