辐型磁钢双机械端口电机是一种新型结构的双机械端口电机，其独特的电磁耦合特性有利于提高系统的整体性能，但其内、外电机之间的较强耦合也增加了其控制难度。该文针对其控制问题，研究内、外电机的解耦控制方法。首先，基于辐型磁钢双机械端口电机的数学模型进行分析推导，理论上证明其存在较强耦合的内、外电机仍然可以采用直接转矩控制方法进行控制，并根据负载角与电磁转矩的单调性要求，推导出采用直接转矩控制方法所需满足的条件；然后，采用基于空间矢量调制的直接转矩控制方法，实现辐型磁钢双机械端口电机的内、外电机解耦控制，验证试验结果显示，内、外电机基本实现转矩独立控制，达到良好的解耦控制效果。

The dual mechanical ports machine (DMPM) with spoke type permanent magnet (PM) arrangement is a new type of DMPM. Its unique electromagnetic coupling characteristics are beneficial for the improvement of system performance, but the coupling between its inner motor and outer motor also makes it difficult to control in the meantime. In allusion to the control problem in DMPM with spoke type PM arrangement, the decoupling control of its inner and outer was researched in this paper. Firstly, based on the mathematic model of DMPM with spoke type PM arrangement, it was theoretically proved that the inner motor and the outer motor could be controlled by the direct torque control (DTC) method in spite of the electromagnetic coupling between them, and the condition which should be met in control was derived according to the requirement for monotonic relationship between the load angle and the electromagnetic torque; and then the decoupling control between the inner motor and the outer motor of DMPM with spoke type PM arrangement was accomplished based on space vector modulation direct torque control (SVM-DTC) method. The results of verification experiments show that the independent torque control for the inner motor and the outer motor is realized, i.e., the decoupling control between them is realized.
