摘要

双凸极永磁(DSPM)电机是一种新型的交流无刷电机，具有功率密度高、调速范围宽、结构简单等优点。为了提高系统的可靠性和容错性能，本文提出了一种新的双通道12/8极DSPM电机调速系统。在对所提出的冗余DSPM电机进行全面介绍的基础上，设计了闭环控制方案。电机驱动器采用数字信号处理器(DSP) TMS320F2812进行速度、位置和电流的反馈控制。速度和位置反馈由一个绝对光学编码器获得，而霍尔传感器实现感应电流。基于原型DSPM电机进行运行性能仿真，结果表明，在相同故障条件下，双通道DSPM电机驱动比传统单通道DSPM电机驱动具有更高的可靠性和更好的运行特性

Improvement in Reliability of Doubly Salient Permanent Magnet Motor Drive

The doubly salient permanent magnet (DSPM) motor is a novel type of AC brushless machine and it offers advantage of high power density, wide speed range and simple structure. To improve the reliability and fault-tolerant performance, a new dual-channel 12/8-pole DSPM motor speed-adjustable system is proposed in this paper. With the comprehensive introduction for the proposed redundant DSPM motor, a close loop control scheme is designed. The motor drive is developed with speed, position and current feedback control using a digital signal processor (DSP) TMS320F2812. The speed and position feedback are obtained from an absolute optical encoder, whereas Hall transducer is implemented to sense the current. The operation performance simulation is conducted based on a prototype DSPM motor and the results show that the dual-channel DSPM motor drive offers higher reliability and better operation characteristics than the traditional single channel motor drive at the same fault condition
