Torque load control system and method

摘要

A machine may include a torque producing system, and a torque consuming device including load controls operable to generate a request for torque. The machine may also include a control system coupled to the torque producing system and the load controls. The control system may be operable to receive the request for torque, determine a torque limit based on the requested torque, and communicate the torque limit to the load controls, the load controls being operable to adjust operation of the torque consuming device based on the torque limit.

主权项

1. A machine comprising:
a torque producing system; one or more torque consuming devices operable to exert a torque load on the torque producing system; a control system coupled to the torque producing system and the one or more torque consuming devices, the control system configured to limit operation of the one or more torque consuming devices to prevent a speed of the torque producing system from falling below a predetermined speed, the control system including
a torque error estimator, andone or more electronic devices operable to sense operating conditions of the torque producing system and the one or more torque consuming devices, and provide torque data to the control system based on the sensed operating conditions, the torque error estimator being operable to compensate for error in the torque data.
