In this paper, we investigate a new method to analyze electrocardiogram (ECG) signal, extract the features, for the real time human identification using single lead human electrocardiogram. The proposed system extracts special parts of the ECG signal starting from the P wave, the QRS complex and ending with the T wave for that we used the multiresolution wavelet analysis. Different features are selected...
In this study, we proposed an analysis method of ElectroMyoGraphic (EMG) signals in order to diagnose and to identify neuromuscular pathologies (i.e.; myopathy and neuropathy). Analysis is performed fully automatically without expert assistance and without prior segmentation of muscle contractions. The method is based on Huang-Hilbert transform (HHT) which is a data-driven algorithm that decomposes...
This paper is concerned with the design of a robust position Backstepping tracking controller for a permanent magnet synchronous motor (PMSM). A Backstepping control law is designed from the input-output linearization of the PMSM model, written in d-q coordinates. This controller is adapted via the estimation of the unknown load torque and friction effects. A linear extended state observer is devised...
This paper presents a novel centralized cooperative scheme which combines compressed sensing (CS) method based on the analog-to-information converter (AIC) with statistical and graphical chi-square Quantile-Quantile (QQ) plot detector. The received signal at every cognitive radio (CR) user in the presence of Additive-White-Gaussian-Noise (AWGN) and intentional interference attack signal (jamming)...
In this paper, two approaches to speed estimation, presented in the literature, for a sensorless control of double star induction machine. We will discuss briefly the advantages, disadvantages, and limits of use of these techniques. We will then apply these two sensorless control techniques to the double star induction machine. The simulation results obtained showed that the speed sensorless vector...
In this paper simulation studies have been conducted using Simulink/MATLAB software in order to investigate the impact of STATCOM on the positive-offset mho element loss of excitation (LOE) protection scheme in synchronous generator. The obtained results show that the operation of the positive-offset protection scheme takes more time under the integration of STATCOM in the transmission line. Moreover,...
In this note, an adaptive fuzzy logic control (AFLC) strategy based on active sliding mode theory is considered to control a class of chaotic fractional-order systems. The main contribution in this work is the use of a saturation function to eliminate the chattering action in the control and surface signals. The nonlinear fractional order chaotic systems are identified using fuzzy logic sets. Based...
In this paper, a Distance-Weighted K Nearest Neighboring (DW-KNN) topology is proposed to study self-organized aggregation as an emergent swarming behavior within robot swarms. A virtual physics approach is applied among the proposed neighborhood topology to keep the robots together. A distance-weighted function based on a Smoothed Particle Hydrodynamic (SPH) interpolation approach is used as a key...
A design of a feed-forward-based fractional-order model reference adaptive control (FO-MRAC) compensator using a modified MIT rule to control a DC-DC boost converter is presented in this work. As the plant is non-minimum phase, an implementation of the so-called parallel feed-forward configuration is required to make the plant satisfy ASPR (almost strictly positive real) conditions that in turn, allows...
This paper gives details of our electrical engineering program efforts to introduce software/hardware design concepts and tools in senior-level and senior-design applications. In this paper we present a simple architecture for the very high development language (VHDL) implementation of a variant of RLS algorithm where adaptive filter coefficients and filtering error are both estimated block wise....
This paper presents a study of a printed X-shaped monopole antenna. The analysis has started from considering a strip fed conventional single band Rectangular Microstrip Antenna (RMSA) resonating at 2.45 GHz commonly used in WLAN applications. The antenna has been transformed to a monopole structure that has yielded a larger bandwidth. In the second part, triangular slots were introduced to the RMSA...
In the recent years, mobile wireless technology has invaded the computer domain with the increased evolution of mobile devices in computing power, storage capacity, and other richer functionalities. Those devices are no longer restricted to phone calls and messages, but also for the access to internet (via WiFi, 3G, 4G …) and exchanging data via Bluetooth. On the other side, we have the great success...
This paper deal with the problem of H∞ robust fault estimation for discrete time nonlinear system with a sector bounded nonlinear additive terms and multiple bounded state delay using the Takagi-Sugeno (T-S) fuzzy model. A fuzzy-fault estimation observer (FFEO) design is proposed to achieve fault estimation of T-S state delay models using fuzzy Lyapunov functions (FLF) with actuator and sensor faults...
The aim of this work is to propose an experimental platform to perform tests on mobile robot systems. The first stage of this work is to build a small arena equipped with a camera and a central computer able to communicate with tested robots. Then, we developed a program to process the images acquired by the camera to locate the robot based on the Hough and KLT calibration algorithms. The second phase...
