A method of controlling operation of an electric machine includes: calculating a voltage-based torque limit based on a voltage constraint of a direct current (DC) bus supplying power to an inverter for powering the electric machine; calculating a current-based torque limit based on a motor current limit; determining a final torque limit based on the voltage-based torque limit and the current-based torque limit; determining a limited command torque based on a torque command and the final torque limit; and generating at least one current command based on, at least, the limited command torque. A control system for controlling operation of an electric machine is also provided.
