摘　　要：针对隐极式永磁直线同步电机凸极效应不明显的特点,提出了基于动子附加高频绕组的永磁直线同步电机的动子位置和速度测量新方法。通过对基于动子附加高频绕组的动子位置和速度测量原理的分析,建立了其数学模型,并在此基础上设计了以TMS320F2407处理器为核心的动子位置和速度的检测系统。侧重介绍了高通滤波器、带通滤波器、移相电路、加法电路和鉴相器等的设计。实验表明,该装置既能保证低速时测量的准确性,也能保证高速时测量的快速性,且具有结构简单、价格低廉、快速性好、测量精度高等优点,特别适宜于由三相交流永磁直线同步电机驱动的长行程伺服系统或运输系统。A new method is put forward to detect the mover position and speed for non-salient pole permanent magnet linear motor（PMLSM） based on the additional high-frequency windings of mover.The mathematical model is derived through the analysis of the mover position and speed detection principle,and the mover position and speed detection system of the non-salient pole PMLSM is designed centred on TMS320F2407DSP processor.The design of high pass filter,bandpass filter,phase shift circuit,summing circuit and phase detector are introduced.The experimental results show that the designed detection system is capable of precisely detecting the mover position and speed at the low speed and possessing fast dynamic response at the high speed,has the advantages of simple structure,low cost,fast response and high precision,and is suitable for long stroke servosystem and transportation system derived by non-salient pole PMLSM.
