Induction machines play a important role in industry and there is a demand for their reliable and safe operation. Different failures occurs in induction machines gives excessive down times and generate large losses in term, and this motivates the condition monitoring of induction motors. The condition monitoring includes taking measurements on three phase induction motor when it is operating in...

This paper focuses on the modeling of a cage induction machine drive under direct-field oriented control, also referred to as flux-vector control. The interest is to create a behavioral model of an induction machine drive under field orientation for sytem simulations since field-oriented control is now commonplace in commerical adjustable speed drives. First, the 3phase induction machine model ...

This study investigates the simple vector control of a 3-phase squirrel cage Induction Motor (IM) under open-circuit fault (faulty 3-phase IM). It was shown that it is needed to supply the stator windings with unbalanced currents to remove the oscillating term of the machine electromagnetic torque. The vector control system is based upon Field-Oriented Control (FOC) that has been adapted for th...

The paper presents a method for parameters estimation of squirrel cage induction motor. The statespace model of the system can be decomposed in two quasi-decoupled systems because the dynamic of electrical system and the one of the magnetizing system are different. It is used a multitime scale decomposition to obtain reduced operational reactances. In the experiments the induction machine is at...

Model predictive current control (MPCC) has recently become a viable alternative for multiphase electric drives, because it easily exploits the inherent advantages of multi-phase machines. However, prediction in MPCC requires high number voltage vectors (VVs), being therefore computationally demanding. In that regard, this paper proposes efficient an asymmetrical six-phase induction machine dri...

This paper proposes a design of a speed control of three phase induction motor fed from wind turbine using genetic algorithm. The wind turbine acts as a prime-mover for doubly fed induction generator. To make the system stable, proper monitoring is required or sometimes an auxiliary system can also be a good option, which can support the primary system during undesirable conditions. The three p...

Three-phase induction machines are generally used as motors for many industrial applications and all this is due to its simple construction and other advantages in contrast to other machines. Popularity of these motors has resulted into a lot of research including the transient behavior of the machine. Literature survey reveals that most of the researchers adopted only a single reference frame ...

Abstract—Multiphase Induction Machine (IM) is normally controlled using rotor field oriented vector control. Under phase(s) loss, the machine currents can be optimally controlled to satisfy certain optimization criteria. In this paper we discuss the performance of double manifold sliding mode observer (DM-SMO) in Sensorless control of multiphase induction machine under unsymmetrical condition (...
