A hydraulic power system circuit can be divided into the following basic function modules: a power supply, consisting of a hydraulic pump reservoir and accumulator; an input signal interpreter, to receive and transduce the input control signals; a controller to manage the direction, flow rate, and pressure of the fluid flow; a protection module, consisting of relief valves and filters, to ensure against damage or contamination; a feedback module, consisting of the transducers that sense and transmit the feedback control signals to the control module; and an output actuation module, consisting of linear actuators (cylinders) or rotary actuators.
