| Abstract |
This paper presents an accurate and robust method of estimating rotor position for an IPM (Interior
Permanent Magnet) drive system for EV/HEV (Electric Vehicles/Hybrid Electric Vehicles) applications.
The importance of encoderless technique for electric propulsion drives has been highlighted in the present
study. Stability and dynamic behavior of the position estimation is critical in consumer-oriented traction
applications. The paper provides experimental results, which demonstrate an excellent performance of
the proposed control algorithm. The goal of this paper is to present an encoderless (or position
sensorless) control method for EV/HEV propulsion drives which works over the entire torque-speed
range including zero mechanical speed. The method combines two rotor position estimation techniques
to fully cover both low (incl. zero) and high-speed ranges. Experimental results demonstrate excellent
performance. |
