multiphase system

Multiphase system has many similarities with three-phase system in principle, but also many new features. So there are still some problems in theory and practices which are worth research and need to be improved.

多相系统与三相系统在原理方面既有相似之处，又引入了很多新的内容，在控制理论和实践应用方面，仍存在较多值得研究和有待完善之处。

It can be seen that the proposed theory greatly generalizes the traditional transformation theory for three-phase circuit, and then, is in favor of establishing a theoretical foundation for harmonic detection, motor control, and fault diagnosis of multiphase system.

可以看到，该变换可以很好地包含传统的三相电路的坐标变换理论，而且它有助于建立多相电路谐波检测、多相电机独立控制、多相电路故障诊断等应用的理论基础。
