摘　　要：研究表明,双机械端口电机内外气隙的电磁场存在严重的耦合,这种电磁耦合影响了内外转子的独立运行特性。本文首先针对两种不同结构形式的永磁型双机械端口电机的耦合特性进行了研究,分析了包含电磁耦合的双机械端口电机数学模型,阐述了耦合的本质。接着基于李雅普诺夫稳定性理论提出一种新的电磁解耦控制算法,可以将4输入4输出的多维系统分解为两个2维传统电机系统,达到内外转子独立控制的目的。最后仿真和实验验证了这种算法的有效性。The dual mechanical port electric machine （DMPM） is a new breed of electric machines. The two ports can input or output mechanical energy freely, working in motor or generator mode at the same time respectively. But field couplings exist between the inner and outer air-gaps, which affects the performances of the two mechanical ports greatly and brings much trouble in controlling. This paper studies the characteristics of the field coupling in two different permanent magnet DMPM motors. The DMPM model inducing the field coupling is analyzed. A linear decoupling control algorithm of DMPM is presented, based on which a four-dimension system thus can be converted into two two-dimension systems. The Lyapunov equations are constructed to prove the stability of the algorithm. Simulations and experiments are carried out. The results prove that the algorithm can decouple the system effectively.
