Frame anti-vibration control for sensorless IPMSM-driven applications

In the case of compressors, frame vibrations cause significant noise problems. In former research, several solutions are presented based on additional sensors, such as accelerometers. However, since the use of sensors includes negative aspects such as high cost and more space, the research on additional sensorless skill is a hot point. In this paper, a novel sensorless anti-vibration system for PMSM-drive applications called Specific Component Reduction System (SCRS) is proposed. This system uses a novel controller called SCRC instead of repetitive controller. The stability of SCRS is analyzed. Experimental results show the effectiveness of the proposed system.
