摘要
电力推进船舶是未来绿色船舶的重要发展方向。永磁同步电动机的一系列优点使其适合作为电推船的推进电机。船舶工作环境的恶劣使得无传感器控制技术在船舶电力推进永磁电机中具有较强的实际意义。目前,无传感器控制技术主要分为中高速和低速两部分,复合控制算法可用于电机全速域范围进行位置和转速估计。
Electric propulsion ships are an important development direction of green ships in the future. The permanent mag- net synchronous motors （PMSM） , with many advantages, are applicable to marine electric propulsion system. Due to the hostile working conditions on ships, the application of sensorless control in the PMSM control is of great practical significance. So far, the main sensorless control algorithms used in the medium and high speed are direct calculation methods, back electromotive force （back-EMF）, observers, model reference adaptive system （MRAS）, neural network control method, etc. And the main sensor- less control algorithm used in the low speed is high frequency injection （HFI）. The compound sensorless control algorithms can be used in the estimation of rotor position and PMSM speed.
