Abstract:
1. A method of controlling a motor, comprising: monitoring a pressure in a circuit supplying a pressurized fluid to the motor; determining a difference between the monitored circuit pressure and a desired circuit pressure; determining an actuator command for an actuator that is capable of adjusting a pressure of the pressurized fluid supplied to the motor, the actuator command being independent of a position of the actuator; operating the actuator based on the actuator command; where the actuator command relates to at least one of a desired pressure in the actuator and a desired force acting on a piston of the actuator; determining whether the difference between the monitored circuit pressure and the desired circuit pressure is above a threshold; and determining an adjusted actuator command based on at least one operating parameter of at least one of a pump and the motor when the difference between the monitored circuit pressure and the desired circuit pressure is above the threshold.
