Multiphase variable speed electric drives are employed in applications where the reduction in the total power per phase and the highest level of overall system reliability is required. Most of the literature on five-phase induction motor (IM) drive deals with field oriented control, direct torque control, and other non-linear control such as backstepping method. This study deals with the theoretical...
In this paper, a new sliding mode observer is developed for the indirect rotor flux oriented control (IRFOC) of a Five-phase Induction motor drive. Numerous observer structures for Five-phase induction motor drive is presented in the literature with acceptable performances. However, the objective of this work is to develop and test another family of observers based on the sliding mode approach. This...
Motor drive system is considered the most important asset in industrial applications. Detection of broken rotor bars has long been important but difficult job in detection area of incipient motor faults. The need for highly efficient motor control drive systems becomes more and more important. Motors are controlled in closed-loop or open-loop modes of operation. This paper develops a novel approach...
Multiphase electric drives have been investigated and proposed for applications where the highest overall system reliability and the reduction in the total power per phase are required. This paper deals with the high performance Backstepping control strategy which is based on laws allowing an explicit control of system stability in closed-loop operation of five-phase induction motor drives. This control...
The paper presents closed-loop ac drive with 5-phase induction motor operating with voltage source inverter and sine-wave filter. The motor supply voltages and currents have sinusoidal shape. For well known adjustable electric drives the field oriented control method with flux and speed control can be applied. In the presence of output filter both control and estimation algorithms should be modified...
A method for fault detection and diagnosis of stator inter-turn short circuits and unbalanced supply voltages for three phase induction machines is presented. The method is based on the analysis of the ratio of third harmonic to fundamental FFT magnitude component of the three-phase stator line current and supply voltage to detect different insulation failure percentages at different load conditions...
The design of the speed controller is important from the point of view of imparting desired transient and steady-state characteristic to the speed-controlled permanent magnet synchronous motor (PMSM) drive system. The design and analysis of a vector-controlled closed-loop permanent magnet synchronous motor (PMSM) drive is presented in this paper work. The effect of different factors like the time...
The paper proposes diagnostic technique for identifying rotor broken bar in speed sensorless three-phase induction motor drive system. Experimental data is collected for healthy and faulty motor with two rotor broken bar. The collected data is first processed using Wavelet packet 1-D transformation to extract the statistical information. The statistical information thus obtained is used to train the...
