Abstract

Speed sensorless permanent magnet synchronous motor torque and flux tracking control algorithm is presented. Proposed approach addresses the problem of operation at both, low and high speed. The idea is realized using a nonlinear closed loop rotor flux observer and stator resistance adaptation algorithm. The analysis of the proposed method is included. The major attention is paid to torque control and then the developed approach utilized for speed control. Such control scheme was implemented on a DSP system and verified experimentally.
