Detection Of Static Eccentricity Fault In Psh Induction Motor By Using External Magnetic Flux Density
(University of Eloued جامعة الوادي, 2016-09-01) Halem, N.; Zouzou, S. E.; Ghodbane, H.
The objective of this paper is to make a clear and thorough investigation about the effectiveness of Motor Current Signature Analysis (MCSA) for detecting default indexes of static eccentricity in (Principal Slot Harmonics) PSH induction motor. The obtained results using traditional technique (MCSA) are compared with spectrums of external magnetic flux density extracted from healthy and faulty motors. The work is carried out with transient finite element method (FEM) simulations considering motor operation under nominal mechanical load, the notching nature of stator and rotor and the non-linearity behavior of ferromagnetic material are taking into account.
Experimental Validation Of A Dual Loop Control Of Two Phases Interleaved Boost Converter For Fuel Cell Applications
(University of Eloued جامعة الوادي, 2016-05-01) Kraa, O.; Ghodbane, H.; Saadi, R.; Ayad, M. y.; Becherif, M.; Bahri, M.; Aboubou, A.
In this paper, a modelling, an implementation and a control of a dc-dc converter structure called “two phases Interleaved Boost Converter (IBC)” will be presented. This topology is widely used in order to reduce the input current ripples and the size of passive component with high efficiency. The control of the IBC converter is designed by dual loop control that contains a voltage loop with a linear PI controller and a fast current loop with a non-linear sliding controller to ensure a good tracking in steady state and fast performance in transient state. The proposed control loop has been validated, first by the simulation results under Matlab-Simulink and after by the experimental results using a small-scale test bench with the dSPACE-1104 card.
