【摘要】：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。
[Abstract]:The dual mechanical port motor of the radial magnetic steel is a new type of double mechanical port motor. Its unique electromagnetic coupling characteristics can improve the overall performance of the system, but the strong coupling between the external motor also increases the difficulty of control. The mathematical model of the dual mechanical port motor of type magnetic steel is analyzed and deduced. It is proved theoretically that there is a strong coupling, and the external motor can still be controlled by direct torque control method. According to the monotonicity requirements of the load angle and electromagnetic torque, the conditions needed to be satisfied by the direct torque control method are derived. Then, the use of the direct torque control method is derived. Based on the direct torque control method of space vector modulation, the internal and external motor decoupling control of the dual mechanical port motor of the radial magnetic steel is realized. The test results show that the inner and outer motor basically realize the torque independent control and achieve good decoupling control effect.
