Abstract: A sliding mode observer and fractional-order phase-locked loop (FO-PLL) method is proposed for the sensorless speed control of a permanent magnet synchronous Motor (PMSM).The saturation function is adopted in order to reduce the chattering phenomenon caused by the sliding mode observer. In this proposed FO-PLL, method, a regulable fractional order r is involved, which means that the FO-PLL provides an extra degree of freedom. In fact, the conventional phase-locked loop (PLL) applied in sensorless PMSM control can be seen as a special case of the proposed FO-PLL. By selecting a proper fractional order r a better performance may be achieved. The computer simulation results demonstrate the effectiveness of the proposed method.Key words: fractional calculus; fractional order phase-locked loop; sensorless control; sliding mode observer; permanent magnet synchronous Motor; speed controll

简介设计者根据对环境的需求,希望能不断开拓高级电机控制技术,用以制造节能空调、洗衣机和其他家用电器产品。到目前为止,较为完善的电机控制解决方案通常仅用作专门用途。然而,新一代数字信号控制器(Digital Signal Controller,DSC)的出现使得性价比高的高级电机控制算法最终成为现实。例如,空调需要能够对温度作出快速响应以迅速改变电机的转速。因此,我们需要高级电机控制算法,以制造出更加节能的静音设备。在这种情况下,磁场定向控制(Field Oriented Control,FOC)脱颖而出,成为满足这些环境需求的主要方法。本应用笔记讨论了使用Microchip dsPIC2 DSC系列对永磁同步电机(Permanent Magnet Synchronous Motor,PMSM)进行无传感器FOC的算法。
