Speed Sensorless Control of PMSM for Noise Rejection Using Evolution Strategy
초록
Most of sensorless algorithm are based on motor equations where it is necessary to find the phase voltage and current. However, measurement error and environmental noise deteriorate the accuracy of speed estimation of PMSM. This paper investigates speed sensorless control of PMSM for noise rejection in harsh environment. The proposed algorithm is based on the interaction between electrical parameter and random noise. The evolution strategy is used for minimizing the noise effect. The proposed algorithm is verified through simulation and experiment.
