In this paper, magnetic field analysis of a new doubly salient permanent magnet (DSPM) motor is carried out based on finite element method (FEM). Hence, the corresponding static characteristics, including PM flux linkage, self-inductance, mutual inductance, and static torque are deduced (the interaction between the PM field and armature field are taken into account). New methods for measuring the motor inductance are also proposed. The theoretical analysis is verified by experimental results.

【期刊论文】New Self-Tuning Fuzzy PI Control of a Novel Doubly Salient Permanent-Magnet Motor Drive
程明, Ming Cheng, Senior Member, IEEE, Qiang Sun, and E. Zhou

In a doubly salient permanent-magnet (DSPM) motor drive, it is difficult to get satisfied control characteristics by using a normal linear proportional plus integral (PI) controller due to the high nonlinearity between speed and current or torque. Hence, a new self-tuning fuzzy PI controller with conditional integral, which is performed by a single-chip N87C196KD, is proposed. The initial parameters of the controller are optimized by using genetic arithmetic. Simulation and experiments on the newly proposed 8/6-pole DSPM machine have shown that the proposed new self-tuning fuzzy PI controller offers better adaptability than the normal linear PI control and that the developed motor drive offers better steady-state and dynamic performances.

In this paper, various flux-weakening techniques available for wide speed operation of the doubly salient permanent magnet (DSPM) motor are reviewed. A new split-winding topology capable of widening the speed range is proposed, which is valid not only for the DSPM motor with stationary PMs, but also for that with rotary PMs. Based on the parameters obtained by finite element analysis, the performance of the proposed DSPM motor is analyzed. The results show that this motor combines the features of wide speed range, high efficiency, simple structure, and low cost.

【期刊论文】基于电流谐波注入的磁通切换永磁电机定位力矩补偿方法
程明, 贾红云, 花为, 赵文祥

磁通切换永磁电机具有功率密度高、输出转矩大、反电动势正弦等优点,而较高的气隙磁密与定转子双凸极结构会产生较大的定位力矩。定位力矩会引起电机运行时的转矩脉动、振动和噪声问题,从而限制了磁通切换永磁电机的应用。从控制角度出发,提出一种新型的采用电流谐波注入法补偿定位力矩的控制策略,即通过注入谐波电流产生的转矩抵消定位力矩中的基波与二次谐波分量,从而达到补偿的目的。通过半实物仿真平台dSPACE实现了该控制算法,并在一台2kW磁通切换永磁电机的驱动系统上验证了所提出补偿控制方法的有效性。该控制方法也可拓展应用到其它反电动势为正弦且定位力矩较大的永磁电机驱动系统。
