Abstract: The embodiments of the present disclosure relate to a radar control device, method and system.

Abstract: A flow generator includes pumps operated by motors to generate an amount of a hydraulic fluid, a proportional hydraulic control valve to control output hydraulic pressure according to the amount of the hydraulic fluid, a pressure sensor to detect the output hydraulic pressure, and a hydraulic servo loop controller to which a required hydraulic pressure and a required amount of fluid are input by a user. Based on a feedback signal representing the output hydraulic pressure, the controller generates a pressure control signal for controlling the proportional hydraulic control valve based on the required hydraulic pressure and a change in the output hydraulic pressure. It also generates an RPM input signal for controlling a motor's RPM.

Abstract: Disclosed are a mobile hydraulic generator having rapid response by scattering a small motor for generating a flow of fluid and a small pump, and a control method thereof. The mobile hydraulic generator includes: a flow generator including n pumps operated by n motors to generate an amount of a hydraulic fluid; a proportional hydraulic control valve to control output hydraulic pressure according to the amount of the hydraulic fluid; a pressure sensor to detect the output hydraulic pressure; and a hydraulic servo loop controller to which required hydraulic pressure and required amount of fluid are input by a user, to which feedback the output hydraulic pressure, to generate a pressure control signal for controlling the proportional hydraulic control valve based on the required hydraulic pressure and a change amount of the output hydraulic pressure and to generate an RPM input signal for controlling RPM of the n motors.
