Multiphase induction machine modelling represents a crucial research topic for both control and performance evaluation purposes. Generally, multiphase machines are preferably modelled using the vector space decomposition technique with some assumptions to simplify mathematical model. However, different sources of non-linearities, including low order harmonics mapped secondary subspaces, cross-c...

The article aims at optimizing six-phase induction generator-based renewable energy systems (6-phase IGs or dual star generators) through a novel nonlinear optimal control method. Six-phase generators appear to be advantageous compared three-phase synchronous asynchronous power generators, in terms of fault tolerance and improved generation rates. dynamic model the generator is first written mu...

This paper develops an inner stator current controller based on enhanced reaching-law-based discrete-time terminal sliding mode. The problem of tracking currents with high accuracy while ensuring the robustness a six-phase induction motor in presence uncertain electrical parameters and unmeasurable states is tackled. unknown dynamics are approximated by using time delay estimation method. Then,...

Abstract The induction motors are back bone of the modern industry and play very important role in manufacturing transportation sectors. motor faults mainly classified into internal such as inter turn short circuits , broken rotors external over load, voltage asymmetry supply voltage. identification type fault is for safe operation preventing risk machine failures. In this work, a Bidirectional...

This paper presents a neural network predictive controller for three phase inverter fed induction machine speed control. Thus the three phase inverter fed induction motor drive has been simulated with and without step change using NNP controller. The performance comparisons of neural network predictive controller are achieved with the help of IAE (Integral absolute error) and ITAE (Integral tim...

Virtual voltage vectors (VVV) have been used for the control of multi-phase induction machines, where different sub-spaces appear related to torque production and losses generation. In literature, several sets VVV used, aiming at reducing harmonic content while maintaining a low computational burden. This paper proposes use regulate stator current drives using finite-state model predictive cont...

Multiphase machines are often chosen due to their enhanced fault tolerance. Six-phase ones especially convenient because they may be fed by off-the-shelf three-phase converters. In particular, those with symmetrical windings offer superior postfault capabilities. On the other hand, estimation of stator resistance is important for purposes such as thermal monitoring and preserving control perfor...
