Abstract Position sensorless vector control has been applied to compressor drive systems using an IPMSM to realize higher efficiency. In this paper, reduction control of cyclic speed change is proposed in order to achieve improved performance, including low vibration and low acoustic noise. Designing a speed estimator by using an adaptive observer with a wide frequency band, the fundamental frequency component of the cyclic speed change is calculated by a bandpass filter. The proposed compensation method recognizing the fundamental component can reduce the cyclic speed change to an acceptable level. The principle of the compensation method is presented along with experimental results. © 2009 Wiley Periodicals, Inc.
