Adaptive Torque Control Circuit and Method of Operation

摘要

A circuit controls a polyphase alternating current electric motor with adaptive adjustments to voltage magnitude and voltage frequency when it receives measurements of wheel slip and wheel skid. The apparatus receives target torque requests as well as sensor data from a wheel and local motion and acceleration detectors. When the target torque is not attainable because of loading or loss of traction, the circuit adaptively determines and provides an attainable torque and transmits the attainable torque value which enables other target torque requests to be amended.
