“…In the reverse effects, the variation of a parameter or a mechanical constant of a material gives a modification of its magnetization, where the initial embedding of this material in a magnetic field is not conditional. The two magnetic and mechanical domains are coupled thanks to this material (Mohammadi and Esfandiari, 2015).…”

Asynchronous machines are omnipresent in automated production systems, due to their robustness and ease of use. These electric motors, however, also concede faults (e.g. short-circuit between turns) leading to unplanned stoppages. Defects with their effects are reflected in the magnitudes of the motors, mainly in flux, current, speed and torque. Our research work in this article presents a contribution of a new approach to the fault tolerant control. This simple and efficient method based solely on the measurement of the electrical energy applied by the magnetostrictive material requires expert knowledge in the field of intelligent materials. In this work, our method is focused on an additive term in the backstepping control that is based on the error of the current during the appearance of the default and the energy recovered by magnetostrictive sensors and the adaptive gain of the Kalman filter. This method improves the performance of backstepping control to maintain the operation despite the appearance of defects. The target is to ensure a minimum performance level of the drive system that is malfunctioning. The obtained results have provided useful information on multiple electrical malfunctions and show the overall performance of this complementary methodology for the fault tolerant control.

“…204,205 Due to inductive characteristics of MSM harvester, it does not work well under high resistive load condition. 206 The main drawback of this harvester is the pickup coil dimension. But for most of the cases, MSEH produces higher power density than other EH at low frequency.…”

This study is based on energy harvesting from vibration and deals with the comparison of different techniques. In the present scenario, energy harvesting has drawn the attention of researchers due to a rapid increase in the use of wireless and small-scale devices. So, there is a huge thirst among scientists to develop permanent portable power sources. In the surroundings, a lot of unutilized energy is wasted which can be collected and used for power generation. Research works have been extensively carried out to develop energy harvesting devices catering to the increasing needs of being efficient and economical. Effective energy harvesting mainly depends on the design of the transducer. Different types of design techniques, material properties, and availability of energy harvesters are reviewed in this paper. The paper aims to explore the advantages and limitations of different energy harvesting principles, advances, and findings of the recent past. This study also discusses some of the key ideas for the enhancement of power output. This paper provides a broad view of the energy harvesting system to the learners, which will facilitate them to design more efficient energy harvesting devices by using different principles.

“…Accordingly, one needs to make clear the magnitude of magnetization and magnetic flux density caused by stress. There have been several models developed for describing the mathematical relationship between stress and magnetization of magnetostrictive materials, including linear piezomagnetic equation [36], finite element uncoupled and coupled model [37,38], and the distributed-parameter dynamic coupled model [39]. In the harvester proposed in this paper there is a pre-magnetic magnet near the Fe-Ga beam, therefore, it is necessary to consider the effect of a pre-magnetization field on the Villari effect.…”

Vibration energy harvesting attempts to generate electricity through recycling the discarded vibration energy that is usually lost or dissipated, and represents an alternative to traditional batteries and may even lead to reliable self-powered autonomous electronic devices. Energy harvesting based on magnetostrictive materials, which takes advantage of the coupling characteristics of the Villari effect and the Faraday electromagnetic induction effect, is a recent research field of great interest. Aiming to develop a new type of magnetostrictive energy harvester using Fe-Ga alloy, which is suitable for harvesting the vibration energy from base excitations and free excitations, a Fe-Ga based cantilever harvester was proposed. The energy harvesting performance of the harvester prototype, including its resonance characteristics, open-circuit output voltage-frequency response and amplitude characteristic under base excitation, influence of external resistance, energy harvesting performance under free excitation, the function of pre-magnetization and so on was studied systematically and carefully by experiments. In terms of the volume power density, the harvester prototype without pre-magnetized magnet when in series with the optimal resistor load displays a value of 2.653 mW/cm3. The average conversion efficiency without a pre-magnetic field is about 17.7% when it is in series with a 200 resistance. The energy harvesting and converting capability can therefore be improved greatly once the Fe-Ga beam is highly pre-magnetized. The prototype successfully lit up multi-LEDs and digital display tubes, which validates the sustainable power generation capacity of the fabricated prototype.
