Claim 14:
15. The control system of claim 14, wherein arbitrating between the voltage-based torque limit and the motor current-based torque limit further comprises the instructions causing the processor to:
determine a first motor current-based q-axis current corresponding to a d-axis current having a predetermined minimum value and corresponding to the motor current limit;
determine a second motor current-based q-axis current corresponding to the d-axis current having a predetermined maximum value and corresponding to the motor current limit;
determine a first voltage limit-based q-axis current corresponding to a d-axis current having a predetermined minimum value and corresponding to the voltage constraint of the DC bus;
determine a second voltage limit-based q-axis current corresponding to the d-axis current having a predetermined maximum value and corresponding to the voltage constraint of the DC bus;
determine one of the first motor current-based q-axis current and the first voltage limit-based q-axis current having a lesser value;
determine one of the second motor current-based q-axis current and the second voltage limit-based q-axis current having a lesser value; and
select one of the motor current-based torque limit and the voltage-based torque limit based on the one of the first motor current-based q-axis current and the first voltage limit-based q-axis current having the lesser value and based on the one of the second motor current-based q-axis current and the second voltage limit-based q-axis current having the lesser value.
