MULTIPLE OBJECTIVES OPTIMIZATION FOR ACTIVE PERFORMANCE MANAGEMENT OF SYNCHRONIC ENGINEERING

摘要

A method for controlling the operation of an electric machine includes: determining a voltage-based torque limit based on a voltage limitation of a DC bus (DC bus),which supplies power to an inverter for the power supply of the electric machine; determining a torque limit based on the engine current based on an engine current limit value; Determine a torque limit based on the feed current based on a feed nominal value to supply power to the inverter, the DC bus; Determine a torque limit based on the recuperative current based on a receiving nominal value to receive current from the converter, the DC bus; Determine a final torque limit based on the voltage-based torque limit;the torque limit value based on the motor current, the torque limit value based on the feed current and the torque limit value based on the recuperation current; Determine a limited command torque based on a torque command and the final torque limit; and calculate at least one current command at least on the basis of the limited command torque.
