To verify the validity of the analysis and the feasibility of the proposed control method a set of simulation tests have been conducted using Matlab/Simulink.

Date A point or period of time associated with an event in the lifecycle of the resource 2016-06-15 Description An account of the resource Monitoring methane (CH4) concentration is essential in many industrial and environmental applications. Emission of such gases is indeed important to detect for health, safety and environmental reasons. The major risk in all these areas is an explosion hazard, which may occur if methane reaches its Lower Explosive Limit (LEL) of5% concentration in air. For that reason, it is necessary to develop gas sensors to monitor that methane levels below this value. Due to a weak absorption of methane, this gas is difficult to detect using conventional methods.Hollow core photonic crystal fibers (HC-PBF) have emerged as a promising technology in the field of gas sensing. The strong interaction achievable with these fibers are especially advantageous for the detection of weakly absorbing regions of methane. In this paper, we investigated, by full vectorial finite element method (FV-FEM) in Rsoft CAD environment, the dependency of relative sensitivity on the fiber parameters and wavelength. Consequently, we introduced the optimal structureof an index guiding hollow core photonic crystal fiber capable of measuring methane concentrations down to 0.1%in air. The simulations showed that the sensing sensitivity increased with an increase in the core diameter and a decrease in the distance between centers of two adjacent holes.

Date A point or period of time associated with an event in the lifecycle of the resource 2016-06-15 Description An account of the resource This paper describes the synthesis of a vector fault tolerant control of induction motor drives using an adaptive observer. This observer is used to detect the rotor resistance and flux components using the stator terminal voltages and currents. The rotor resistance is adapted using a new algorithm which does not imply a high computational load. Stability analysis based on Lyapunov theory is performed in order to guarantee the closed loop stability. The rotor resistance is used for the correction of the controllers and the rotor time constant. To verify the tolerance and the applicability of this control, we consider the stator inter-turn fault which is frequently encountered in practice. An analytical method for the modelling of this fault is presented. The equations which describe the transient as well as steady state behavior of unsymmetrical induction machine including the computation of machine inductances are presented. These inductances are calculated analytically using the magnetic field distribution through the machine air-gap. Simulation results are provided to evaluate the consistency and performance of the proposed fault tolerant control of induction motor based vector control.

Today, most of fuzzy logic controls are still implemented on expensive high performance processors. This paper analyzes the effectiveness of a fuzzy logic control using a low cost controller applied to water level control system. The paper also gives a low cost hardware solution and practical procedure for system identification and control. We started, first by identifying the process to obtain its mathematical model. Then we used two methods to control our system (PI and fuzzy control). Simulation and experimental results are presented.

This work applied two diagnostic methods on stator current signal. It is necessary to verify the machine health to avoid any catastrophic damage. The first method uses the fast Fourier transform (FFT) which is generally called motor current signature analysis (MCSA). We carefully verified the spectral content of the stator current to detect BRB fault. The new harmonics allows us to take a good decision about BRB fault. The second method is based on the discrete wavelet transform (DWT). This technique is widely used in the diagnosis field of rotating machinery. According to DWT method, we used the mean square error (MSE) as a good indicator. An experimental test with different conditions of the induction motor has been performed. The experimental results have been exploited using MCSA and DWT methods to achieve a good decision.

Creator An entity primarily responsible for making the resource DJABALI , Sarah AIT HAMOU ALI, Melissa AMMAR, Abdelkarim Date A point or period of time associated with an event in the lifecycle of the resource 2021-03-31 Description An account of the resource Generally, AC-DC conversion system in the power system use the diode-bridge based rectifiers that cannot be reversible and causes high current distortion. Besides, they reduce the power factor and energy quality. recently, the application of three-phase pulse width modulation (PWM) rectifier has been risen quickly due to breakthrough advancement in the power devices. This converter offers sinusoidal input currents and minimized harmonic distortion and unity power factor. This work presents an improved sensorless control for performance enhancement purpose of the PWM-rectifier. The proposed control strategy uses the virtual flux principle with second-order generalized integrator (SOGI) in order to overcome the accompanying drawbacks of using pure integrator of low-pass filters for estimation. The integration of improved virtual flux estimator with direct power control saves the cost of using many voltage sensors which can increase the reliability and effectivity of the control system. Moreover, it improves control robustness and against highly distorted network. The different proposed approaches have been investigated through simulation using MATLAB/Simulink software.

Phase of the functional andtechnical study of which reflects on the aircraft maintenance component, without forgetting the phase ofsynthesis of the landing system mechanisms. The approach presented relates to the description of thedifferent instruments and languages used for the control of vibratory behavior in a maintenance plan. Activedevices are used mainly in systems where the excitation acts permanently on the system and the minimizationof the amplitude of the vibrations is the dominant criterion. This is the reason why it is important to plan andcontrol the technical aspect which will contain the landing system from the point of view of geometry, torques,positions, speeds and accelerations, and trajectories from the mechanism design phase.Keywords: Synthesis of mechanisms, Measurement and Instrumentation, CAD Prototype   Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context https://ajss.dz/index.php/ajss/article/view/4 10.51485/ajss.v6i1.4 Language A language of the resource eng Publisher An entity responsible for making the resource available Laboratory of Signals and Systems, Algeria Relation A related resource https://ajss.dz/index.php/ajss/article/view/4/112 Rights Information about rights held in and over the resource Copyright (c) 2021 ABDELKADER BENMISRA, Hadjira BELAIDI, Abderahmane BELAIDI, Abdelhalim BRAHIMI, Moufida IRKI https://creativecommons.org/licenses/by-nc/4.0 Source A related resource from which the described resource is derived Algerian Journal of Signals and Systems ; Vol. 6 No. 1 (2021): Algerian Journal of Signals and Systems; 61-66 2676-1548 2543-3792 10.51485/ajss.v6i1 Subject The topic of the resource Synthesis of mechanisms,Measurement and Instrumentation, CAD Prototype.

The latter is used to study NBTI phenomenon with measure-stress-measure method, for electric field 5MV/cm < Eox < 7.5MV/cm, and temperatures 27°C < Ts < 120°C. Measurement time has reached 10 us, and a stress-measure delay (switching time) of about a hundred of milliseconds was obtained. However, strengths and weaknesses of the implemented technique have been discussed. Furthermore, the extraction methods: transconductance (Gm), subthreshold slope (SS), and mid-gap (MG), have been implemented and discussed as well. NBTI parameter i.e. Delta Vth, n, gamma and Ea were extracted and compared to other results. A time exponent n of 0.149 has been touched. Activation energy Ea = 0.039 eV and a field factor gamma = 0.41 MV/cm for a stress time ts < 10 s have been obtained.
