For contemporary variable-speed electric drives, the accuracy of machine's mathematical model is critical for optimal control performance. Basically, phase variables multiphase machines are preferably decomposed into multiple orthogonal subspaces based on vector space decomposition (VSD). In available literature, identifying correlation between states governed by dynamic equations and parameter...

This paper presents a detailed recent research trend on multi-phase induction machines, which include multiphase induction motor as well as the multiphase induction generator. Electrical power system developed so far was of three phases since the beginning of the last century but research in the field of multi-phase machines have attracted increased interest in recent years due to the several a...

A simple mathematical model is proposed to compute the steady-state performance of six-phase self-excited induction generators. A mathematical model is formed directly from the equivalent circuit of six-phase selfexcited induction generator by nodal admittance method. The proposed model completely eliminates the tedious work involved in the existing models. Genetic algorithm is applied to solve...

In this manuscript, the high-accuracy stator currents tracking issue is considered for a six-phase induction motor subject to external perturbations and uncertainties due unmeasurable rotor electrical parameter variations. To achieve control goals, common two-cascade controllers structure required type of motor. The first controller in outer loop consists proportional integral regulate speed. T...
