摘要：
In order to achieve the sensorless control of permanent magnet synchronous machine (PMSM), the modeling process of the traditional observers requires the derivation of the state current, which results in noise increase and additional work for the filter design. This paper proposed a back electromotive force (EMF) observer based on a deliberately designed disturbance observer, which was capable of estimating the system disturbance accurately without calculating the state vector derivation or inserting noise filter. The back EMF in the current state function in the stationary reference frame was considered as the disturbance signal, whose estimation result was used to derive the rotor position through an arctangent calculation. A position error compensation self-adjusted with speed was designed for sensorless PMSM control based on the designed disturbance observer. The simulation and experimental results show that the sensorless PMSM control system achieves high performance by using the proposed method with simple selection of the observer gain, self-adjustment and robustness with speed and load variation. © 2016 Chin.
