Decoupling control for five-phase fault-tolerant permanent-magnet motor by using SVM inverse system method

This paper presents a new decoupling control of five-phase fault-tolerant permanent-magnet (FTPM) motor drives, in which support vector machine (SVM) and inverse system theory are incorporated. The inverse system is constructed to compensate the original system into a pseudo-linear system, while SVM is utilized to obtain the inverse system without knowledge of accurate motor model. The proposed FTPM motor drive is verified in Matlab/Simulink environment, showing that the d-axis current and speed of five-phase FTPM motor system are successfully decoupled. Additionally, the proposed motor drive offers fast speed response and high control accuracy.
