Abstract

Coordinate Rotation Digital Computer (CORDIC) is usually used to obtain the angle information without any multiply and division operations. The extended electromotive force (extended-EMF) in the literature shows that the angle error between the rotor reference frame and the assumed reference frame can be estimated from an arctangent function and a division. In this paper, the sensorless control for permanent-magnet synchronous motor (PMSM) is designed and implemented based on the CORDIC algorithm. Compared to the calculation of the arctangent function and division operation, CORDIC-based algorithm is able to save calculating time and memory resource. The provided simulation and experimental results also demonstrate the proposed CORDIC-based sensorless control.
