The purpose of this paper is to compare two methods of computation of image moments and its inverse, the first is the common recursive method based on Krawtchouk polynomials with respect to x, the second is based on Krawtchouk basis and Clenshaw's formula. This paper in a first time will define these methods and in the second time will evaluate these methods and compare it to each other. We finally prove the accuracy of the proposed method in term of time consumed.

The objective of greenhouse climate control is to improve the culture development and to minimize the production costs. In this paper, we propose a comparison between two approaches to modelling and control greenhouse's inside climate. This one is defined by internal temperature and hygrometry. The classical approach is based on a single linear model to describe the dynamic of greenhouse internal climate and using a strategy control to regulate the microclimate inside the greenhouse. The multi-modelling approach aims to reduce the complexity of the system in terms of variables to take into account in modelling and controllers design. Therefore, we have developed two linear models for representing the greenhouse inside climate in two different durations. Those diurnal and nocturnal phases. For the control of greenhouse inside climate based on finite-horizon optimal control, we present two methods. The first one is a classical method and consists of controlling the internal climate by using a single controller for all days. The other one is based on two models and two controllers for nocturnal and diurnal phases. For the needs of simulation purpose, we have used a nonlinear model to describe more effectively the behavior of greenhouse dynamic climate. A successful feasibility study of the proposed controller is presented and simulation results show good performances despite the high interaction between the process internal and external variables. The comparison results confirm the superiority of a multi-modelling approach.

In this paper a single workspace location problem in a polygonal area V is considered. Our objective is to locate a workspace facility so as to minimize the total distance between the facility, the customers and the suppliers. Our approach is based on the consideration of the distance and the importance factor of each customer and supplier. We used the A-distance measurement and the aggregation method theories to represent the real travelled distance in the mathematical modeling. The aim of the study is to determine the workspace location coordinates in the V area.

The Web Winding System (WWS) knows several constraints such as the thermal effects caused by the frictions, and the mechanical effects provoked by metal elongation, that generates dysfunctions due to the influence of the process conditions. A major objective in the web winding system control design is: •To obtain a precise thickness, with the best possible regularity when a sudden constraints occurs. •To achieve stable rolling and ensure strip quality. This work presents the conception of a new law of nonlinear control of the WWS. This is the Backstepping method with introduction of integral actions. Furthermore, the simulation under the Matlab/Simulink software allows the highlighting performance of the control strategy adopted.

The most significant drawback of the grid-connected Doubly-Fed Induction Generator is its susceptibility to grid fault due to its stator windings being directly connected to the grid. The stator and rotor of the DFIG are electromagnetically coupled; therefore, the resulting stator current surge during low voltage dip provokes inrush current at the delicate back-to-back converters and an overcharge of the DC-link capacitor. When rotor current and DC-link voltage increase above their predefined Save Operating Zone (SOZ), rotor converters are damaged and active-reactive power control is consequently lost even after the fault is cleared. In this paper, a robust nonlinear disturbance rejection controller, under the context of Lyapunov stability theory, is first employed to control the Rotor and Grid Side Power Converters under normal grid conditions. Under grid fault, the nonlinear controller is then coupled with active crowbar and DC chopper protection schemes to ameliorate the performance of the DFIG system to ride through fault. Simulation of a 1.5MW wound rotor induction generator under MATLAB/SIMULINK is carried out using the PI-controller (PIC) and Adaptive Backstepping Controller (ABC).

This paper describes an adaptation of the Clonal Selection Algorithm for the single objective Big Optimization problem “Big-Opt”. Indeed, the electroencephalography “EEG” signals are very sensitive to noising effects of artifacts caused by undesirable internal and external electric sources. the main purpose of the Big-OPT problem is to rebuild the recorded signals in the goal of removing the artifacts as maximum as possible. To this end, an optimization problem is defined. To solve it, a modified search strategy is studied and adapted for the Clonal Selection Algorithm in order to enhance its convergence abilities on large scale optimization. To test the performance of the proposed method, experiments have been conducted over the Big-OPT EEG datasets. A comparison with recent state of the art approaches is also included. The study exhibits the competitive performance of the proposed Clonal Selection Algorithm.

Performance analysis of distributed GM-CFAR (Geometric Mean-CFAR) and OS-CFAR (Order Statistic-CFAR) detectors in a Pareto clutter is presented in this work. Because of the nonlinear property of this multidimensional system, the biogeography based optimization (BBO) algorithm is used to obtain optimal thresholds of local detectors. Each CFAR detector takes its own decision and sends it to the fusion center to obtain a final binary decision according to a preselected fusion rule. Optimization requirements of the distributed system are improved using a new expression in integral form of the detection probability. Via computer simulations, the detection performances are investigated in terms of clutter and system parameters for both homogeneous and heterogeneous Pareto backgrounds.

Ball bearings are critical components in rotating machines and the prognosis of their health state is an important policy that increases reliability, availability and safety while minimizing costs. Wavelet Packet Decomposition (WPD) is a widely used method for the analysis of vibratory signals since it allows decomposing them in time and frequency domains. The choice of the analyzing wavelet and its order is an important step that affects the estimation of the Remaining Useful Life (RUL). In this paper, we compared several types of wavelets in order to choose the most suitable for predicting the RUL of the bearings. The utilized selection criteria were the Minimum Shannon Entropy Criteria (MSEC) and Maximum Energy to Shannon Entropy Ratio criteria (MEER). The tests were carried out on several bearings under different conditions where horizontal and vertical accelerations are measured.

This work focuses on a smart algorithm to optimize energy of electric vehicles charging station while considering numerous constraints as the instability of renewable energy sources and the potential limited power given by the grid. The PV array is considered as a basic source of energy to feed the charging station system, directly tied into a voltage DC bus, thus the lithium-ion battery is implemented in this platform to complete the power flow of each potential charging scenario. Moreover, the management algorithm is taking into account the fluctuant power state of both the DC and the AC bus link, and it treats also the state of charge of the batteries in the energy management approach.
