Abstract: A drive control system includes an electric motor, a capacitor, a revolution sensor, a driving device, and a control device. The driving device causes the capacitor to supply electric power to the electric motor to operate the electric motor and causes the capacitor to store the electric power, generated by the electric motor, to brake a turning body. The driving device configured as above is driven by driving electric power supplied from the capacitor. When a charging stop condition is satisfied, the control device stops the driving electric power supplied from the capacitor to the driving device. The charging stop condition is a condition that a turning speed detected by the revolution sensor is a predetermined speed or less while the turning body is decelerating.

Abstract: An electro-mechanical actuation system for a piston-driven fluid pump. The electro-mechanical actuation system includes a plurality of electro-mechanical actuators, and a control system electrically connected to the plurality of electro-mechanical actuators. Each electro-mechanical actuator is configured to operatively couple with a piston of the fluid pump. The control system is configured to determine a target output of fluid to be pumped by the fluid pump, individually control a speed and a phase at which each electro-mechanical actuator actuates the piston, such that the plurality of cylinders collectively pump fluid at an actual output that corresponds to the target output, and in response to detecting an operating condition, individually adjust the speed and/or the phase at which one or more of the electro-mechanical actuators actuates the piston based on the operating condition to thereby cause the actual output of the fluid pump to correspond to an updated target output.
