Abstract
The paper deals with the control of permanent magnet synchronous motors without any mechanical sensor. For this purpose a new flux model (“INFORM model”) is used, working properly at each operating condition, especially at low angular velocity. At higher angular velocity, an e.m.f.-based model is used. A Kalman filter estimates the angular position, the angular velocity and the torque. An optimal state controller is presented which yields good dynamic performance. The system is realized on a digital signal processor.Keywords
