In this work, we propose a new architecture of Network-on-chip (NoC) system with WCDMA codes. A Bipolar CDMA code is used to provide a good system performance and to reduce MAI (Multiple Access Interference). Two structures of receiver are employed, while putting into consideration a thermal noise limitation. On one hand, it has proved, in this paper, that system performance can achieve a BER value less then -90dBm with an acceptable node number. On the other hand, system bandwidth can reach 16Gbit/s with an acceptable SNR compared to wired architecture.

This paper's object is the control and the observation of an induction motor using sliding mode strategy. Therefore, sliding surfaces are proposed to adjust the speed and the square of the rotor flux magnitude. The observer is used to estimate the rotor flux, because it can't be measured in practice. An adaptive algorithm of the rotor's resistance is proposed to improve the robustness of this strategy; this work is based on Lyapunov function to make sliding surfaces asymptotically attractive.

Simulation of Ground Power Supply Unit is very important to test the performance and effectiveness of the systems under different scenarios. It can provide a safe and cheaper test bed to operate and evaluate the performance of the system before realizing it in the physical world. In this paper the effect of switching frequency on the performance of a ground power supply unit based matrix converter is studied. Simulation results from a 7.5KVA converter presented at different switching frequencies.

This paper presents an improved method of rotor flux angle θs estimation for sensorless indirect oriented field control of induction motors based on a phase locked loop (PLL). A PLL is used to estimate the rotor flux angle taking account only the reference speed. The Extended Kalman Filter (EKF) is used to estimate speed and rotor flux. Extensive simulation and experimental tests confirm the effectiveness of the proposed approach.

In this paper, we propose a Sliding Mode Observer (SMO) design method to solve the problem of fault reconstruction for a class of linear systems with output time-delay. A sufficient conditions using Linear Matrix inequality (LMI) optimization and Lyapunov functional are derived to compute the SMO gains and guarantee the stability of the estimation error dynamics. Applying the developed SMO and the equivalent output error injection, actuator and sensor faults reconstructions are obtained. Therefore, these two problems of SMO design and faults reconstruction are numerically tractable via LMI optimization. Numerical example is given to illustrate the validity and the applicability of the proposed approaches.

The major problem of controlling a multi-variable electrical system comes mainly from the lack of information on its structure, which was supposed to always linear, a change in unexpected state may cause system instability, hence the requirement development of a new control structure incorporating nonlinear effects and time-varying phenomena while respecting the desired specifications on their stabilities. A new control scheme for speed induction motors is proposed in the present paper, called "passivity based control (PBC) on the principle of exchange control energy via state feedback was presented it allows to work in several areas. A port-controlled Hamiltonian (PCH) model of the induction motor is deduced to make the interconnection and damping of energy explicit on the scheme. The proposed controller is validated under computational simulations MATLAB.

This paper presents the design procedure of a global fault detection and isolation strategy for complex systems based on bond graph tool. The proposed method consists in establishing a word bond graph model and developing a local observer for each subsystem. The aim of the paper is to deal with the structural interconnection between these observers using structural and causal properties of the bond graph methodology. The results are validated on a DC motor driven by a filter using 20sim.

This paper deals with a Sensorless backstepping controller. In order to improve the robustness of the proposed approach, we estimate the rotor flux components and rotor speed of the induction motor using a sliding mode observer. The backstepping technique is appropriate for such as non linear system. The overall system stability is proved through appropriate Lyapunov functions. Experimental result is presented to prove the effectiveness and validity of the proposed Sensorless control.
