    IPC: B25J9/14

    Abstract: The invention is directed to controlling a hydraulic actuation system (50) having at least one degree of freedom, a prime mover (101), at least one actuation module (110, 120, 130) and a controller (103), with each actuation module (110, 120, 130) including: an over-center variable displacement pump (112 and 113; 601; 801) having a power input connection configured to power the pump from the prime mover (101) and a displacement varying input for varying the displacement of the pump; a displacement varying actuator (111, 121, 131) configured to modulate the displacement varying input of the pump; an output actuator (115) in direct communication with the pump, the output actuator (115) configured to drive a corresponding degree of freedom; and at least one sensor (116, 126) establishing a feedback measurement that represents a force or motion of the output actuator (115).

    Abstract: The invention is directed to controlling a hydraulic actuation system (50) having at least one degree of freedom, a prime mover (101), at least one actuation module (110, 120, 130) and a controller (103), with each actuation module (110, 120, 130) including: an over-center variable displacement pump (112 and 113; 601; 801) having a power input connection configured to power the pump from the prime mover (101) and a displacement varying input for varying the displacement of the pump; a displacement varying actuator (111, 121, 131) configured to modulate the displacement varying input of the pump; an output actuator (1 15) in direct communication with the pump, the output actuator (115) configured to drive a corresponding degree of freedom; and at least one sensor (116, 126) establishing a feedback measurement that represents a force or motion of the output actuator (115). Based on a value of each feedback measurement, the force or motion of the output actuator (115) is regulated by controlling the prime mover (101) and the displacement actuator (111, 121, 131) for the output actuator (115).
