This paper introduces three years of industrial experience with sensorless interior permanent magnet synchronous motor (IPMSM) drive based on high frequency injection method (HFIM). In 2008 the first commercial general purpose inverter with sensorless control based on HFIM was launched. The HFIM enabled the sensorless IPMSM drive to control torque and speed under ultra-low speedregion including zero stator frequency, which brought the expansion of the application field. The feature also realized the position control. Owing to the control performance and the sensorless feature on the reliability and the space-saving, the sensorless drive has been employed to direct drive applications with great expectations. As successful applications, a lift, a compressor, and an injection molding machine are introduced in this paper.
In CBrsystem, the case base is becoming increasingly larger with the incremental learning which results in the decline of case retrieval efficiency and its weaker performance. Aiming at such weakness of CBrsystem, t...
