ABSTRACT:
System and method for high-speed, high-accuracy control of a multiphase motor in a vehicle having a DC power supply in response to a motor command signal, the system being a substantially digital implementation. The system includes programmable digital logic for generating a digital desired phase current signal for a particular motor phase. A signal indicative of the actual current in the particular motor phase is generated. The system includes comparators for comparing the desired phase current signal with the actual phase current signal and generating a digital error signal based on the difference between the desired and actual phase current signals. Additionally, the system includes an inverter, including a plurality of switches, for generating the actual current in the particular motor phase from the DC power supply. Based on the digital error signal, the digital logic generates a digital switch state output signal to control the operating state of the inverter. The system also preferably includes a sensor for providing a motor position feedback signal to the programmable digital logic.
