A Speed Sensorless Vector Control for Permanent Magnet Synchronous Motors using The Integral Binary Observer

초록

This paper presents a speed and position sensorless control of Permanent magnet synchronous motors using an integral binary observer. In order to improve the steady state performance of the binary observer, the switching hyperplane equation of the observer is formed by adding extra integral dynamics to the switching hyperplane equation. The observer structure and its deign method are discussed. The simulation results of the proposed algorithm are presented to demonstrate the effectiveness of the approach.
