Multiprocessor System on Chip (MPSoC) technology can present an interesting solution to reduce the computational time of complex applications. Execute the H.264/AVC encoder on MPSoC architecture, is becoming an interesting point of research that can mitigate its algorithmic complexity and to resolve the real time constraints. In this paper, we present an efficient MPSoC architecture for the intra...

The aim of this paper is to present an improved Direct Torque Control based on the Artificial Neural Networks. Thanks to their advantages, in this paper we proposed the use of Xilinx System Generator toolbox added to Matlab / Simulink. This solution replaces the use of programming language. Obtained results demonstrate that the proposed control is able to obtain high performance.

This paper addressed the analysis and design of a sliding mode observer for a class of uncertain nonlinear systems. We continue to work in [1] that proposed an approach to design the sliding mode control of same system using the control law obtained to analyze our sliding mode observer. The main idea of the paper is the development of a robust observer with respect to the uncertainties parametric...

In this paper, we develop a new control approach for IM. The basic idea of this technic is to make stable the closed loop system in the sense of Lyapunov. This method compared with traditional IM control use a simple calculation by the fact that we obtain a global asymptotic stability. The objective of this control technic is based on an appropriate choice of the voltage control values that guaranty...

In this note, the problem of stabilizing of nonlinear affine system based on concept of modal state feedback control. The key idea is to transform the switched nonlinear system under an arbitrary signal to a switched linear model without resorting to any approximation. Then a control law will be designed to guarantee global stability by the means of Common Quadratic Lyapunav Function (CQLF). The implementation...

The hybrid photovoltaic thermal solar collector (PV/T) offer an interesting alternative to photovoltaic and thermal collectors installed separately, because the absorbed solar radiation is converted into heat and electricity. In this paper a new configuration of hybrid solar thermal collector is designed. We began measuring temperature, electrical power and its influence in a period of time, these...

This paper deals withweak wind energy control in isolated siteswith variedwind speed. It aims to find out new ways to control the DC bus voltage according to a fixed reference regardless of wind speed variations. The different simulation results of all the conversion chains realized under the MATLAB/SIMULINK environment, allowed the evaluation of the suggested system'sperformance.

In this paper, a Hybrid Electrical system for DC loads is proposed. Our system consists of two energy sources, namely Proton Exchange Membrane Fuel Cell (PEMFC) and Ultra-Capacitor (UCap). The given design shows that the transient behavior, which affect the Proton Exchange Membrane Fuel Cell, is eliminated using the Ultra-Capacitor through the Flyback converter. In our system, we consider an available...

In this paper, a review is given of present state of the art about the concept of wireless power transmission i.e., transmitting power as microwaves from one place to another in order to reduce losses during the transmission and distribution of electrical power or also to deliver energy in location where conventional wires are expensive, inconvenient or impossible. This concept is known as Microwave...

Since the beginning of study of the Secure Hash function (SHA), it has been thoroughly studied by designers with the goal of reducing the area, frequency, throughput and power consumption of the hardware implementation of this cryptosystem. The Secure Hash function algorithm has become the default choice for security services in numerous applications. Following the attacks considerable standard SHA-2,...

This paper presents a new delay-dependent and parameter-dependent robust stability criterion for linear continuous-time systems with polytopic parameter uncertainties. This criterion, expressed as set of linear matrix inequalities, The present method incorporates a relaxed parameter-dependent technique combined with a recently proposed idea of introducing slack variables matrices. The present result...

This paper describes experimental implementation to demonstrate that it is physically viable to implement adaptive fuzzy controller-based H∞ tracking for high performance brushless motor drives. The fuzzy controller is based on PI/PD control structure and equipped with an adaptive learning algorithm to achieve H∞ tracking performance with external disturbances. The fuzzy-PI and fuzzy-PD design serves...

This paper is concerned with the simultaneous actuator and sensor faults reconstruction problem using sliding mode observer for polytopic Linear Parameter Varying (LPV) systems. Sufficient conditions in terms of Linear Matrix Inequality (LMI) are derived to guarantee the stability of such observer. A simple filter is introduced to transform the sensor fault into a pseudo-actuator fault scenario and...

This paper presents a validation of a kinematic model of a Humanoid robot via standard Scenarios. The humanoid robot considered is composed of fifteen links associated to twenty-six degrees of freedom. Its 3D anthropomorphic model is derived from Winter's statistical method. Due to the model nonlinearity, initial conditions are carefully tuned and the kinematic model is validated through standard...

This paper presents an innovative way using the design of fault-tolerant control (FTC) systems for induction motor (IM). It will be shown how the nonlinear output regulation theory can be successfully adopted in order to design a regulator able to offset the effect of all possible faults which can occur in IM drives and, in doing so, also for faults tolerant control process. This regulator is designed...

In this paper, a model for Unified Power Flow Controller (UPFC) is suggested with Newton-Raphson power flow program included. The main control of UPFC series element is realized as a combination of the four control functions. The supplementary control of UPFC is added for damping power oscillation. The integrated UPFC model is then incorporated into the conventional transient and small signal stability...
