This paper presents a new approach via MOPSO algorithm to solve optimal Economic Dispatch (ED) via Unit Commitment Problems (UCP). The unit commitment problem can be defined as the scheduling of production of electric power generating units over a daily to weekly time horizon in order to accomplish some objective. The problem solution must respect both generator constraints (such as ramp rate limits and minimum up or down times) and system constraints (reserve and energy requirements and, potentially, transmission constraints). The first function is the production cost. While the second one is the transition cost. A comparative study is conducted to examine the impact of reliability constraint on the optimal solution obtained. The ten machine thirty nine-bus system is used and the results show the effectiveness of MOPSO and confirm its potential to solve the unit commitment problem.

In this work, a model based T-S fuzzy predictive control LMI optimization is introduced. The aim of discrete T-S fuzzy predictive controller is to drive the state of the system to the original state where a stabilizing controller is ensured. The stability of the controlled systems is studied using non quadratic case of the Lyapunov function and adopting of Non-PDC controller. The stability is guaranteed based on the conditions expressed of terms of LMIs. The optimal solution has been obtained at each sampling time. The results are shows the effectiveness of this strategy.

The aim of this work is to provide an alternative that could replace the conventional technique based on the spectral analysis of the line current to detect an unbalance state due to a weak amplitude drop affecting one of the three-phase currents drawn by a squirrel cage motor. From a theoretical investigation, it has been stated that the spectral analysis of the emf induced at the terminals of a simple search coil placed close to the motor frame may be of interest for diagnosis purpose. The experimental results have revealed that this suggested sensory signal provides an excellent fault indicator regardless of the load level.

Demand side management is considered as the next evolution of smart grid technology, it can adjust the time and the quantity of the electricity usage either by shifting the demand during the peak hours or by moving the time of energy use to off-peak periods. The objective of this paper is to develop an efficient load side management strategy for photovoltaic-wind hybrid energy system for an isolated house. The strategy aims to control the non-critical loads of the house based on an efficient analysis of the daily load profile of the house and on the climate data. The simulation result shows the effectiveness of the proposed strategy, as it improves the energy balance of the system and eliminates the energy waste.

Due to nonlinearities and uncertainties, the dynamic characteristics of underactuated systems are very difficult to obtain precisely. In this paper we develop a robust controller based on sliding mode control for the control of a class of underactuated systems. The stability of the proposed controller is proved with the Lyapunov function method. Simulation results made on a flexible link manipulator are given to illustrate effectiveness of our approach.

This paper presents the development of a classical and intelligent control approaches applied to a flexible single-link manipulator robot and compared in terms of input tracking and vibration suppression. Lagrange's equations and finite elements method are combined to compute dynamic model of a flexible link manipulator with one rigid joint. Next, dynamics are itemized to explain flexible link behavior. Then a fuzzy supervisory controller is developed and introduced in the high level of the closed-loop of the flexible manipulator. A generalized predictive controller is then developed and introduced in the flexible system closed-loop to minimize end-point residual vibrations. Simulation results obtained are compared to a Generalized Predictive Controller (GPC) in terms of end-point vibration suppression, input tracking and disturbance rejection. A conclusion encloses the paper.

This work presents a study of the effect of developed hybrid halogen LED solar simulator. The developed system present a affordable solution for research lab's to analyze the solar cells efficiency. Two different light sources were studied and a combination solution was described. The developed system was tested with two different generation of solar cell. Current- Voltage (I-V) solar cell characterization was extracted and compared with different light sources. Incident monochromatic photon to electron conversion efficiency (IPCE) characteristics was determined in order to display the efficiency of the developed solar simulator. The developed system has noticeable improvement in both solar cells types, compared to the use of halogen lamp only.

Industrial environments are becoming more and more dynamic, complex, and uncertain. In such conditions, building safe systems is a major requirement and a big challenge which cannot be achieved without suitable diagnosis tools and methods. The early diagnosis approaches were mostly centralized and done offline. It was then proved that distribution is of a great contribution to realize better diagnosis of complex industrial systems. This paper focuses on Discrete Event Systems (DES) and introduces a distributed approach for online faults diagnosis in DES using Causal Temporal Signatures (CTS). The proposed solution relies on a multiagent architecture where multiple autonomous agents cooperate and coordinate their actions in the diagnosis process.

Broadband power line (BPL) was used for power transmission. In addition to that, it also gives another important benefit; that is data transmission via it also, the main advantage here is being able to use the existing power network infrastructure, means reducing the cost by 60%. However power line system were not designed for high speed data transmission as they consists of various branches and power line elements such as bridges, transformers, in addition to internal effect from their characteristics. In this paper it will study the BPL performance due the line parameters (characteristics) and discuss their effects with frequency increasing.

This paper deals with the problem of Sliding Mode Control (SMC) design for a class of non linear system. Two different control designs are developed for a dynamic system Maxpid. The first type is the define of traditional Sliding Mode (SM) control. The second is the Higher Order Sliding Mode (HOSM) control. These two kinds have the same properties of robustness and precision. Note that the implementation drawback of the first type has a chattering phenomenon. The HOSM control is proposed to reduce the phenomenon. The simulation results obtained from the two types are finally compared in terms of good performances.
