Implementation of a Fuzzy Logic speed controller for a Permanent Magnet DC (PMDC) motor using a low-cost Arduino interfaced with a standard xPC Target MATLAB environment is demonstrated. The Arduino solution is acceptable at kHz sampling frequencies. The study of speed control of PMDC motor based on Arduino and L298N H-Bridge using an artificial intelligence control method, such as Fuzzy PID with...
Training of Artificial Neural Networks (ANN) is an important step to make the network able to accomplish the desired task. This capacity of learning in such networks makes them applied in many applications as modeling and control. However, many of training algorithms have some drawbacks like: too many parameters to be estimated, important calculus time. In this paper, we propose a very simple method...
The purpose of this paper is to design a fuzzy supervisory PID controller using an improved genetic algorithm. The fuzzy controllers are widely used in the recent years due to their results in both tracking and perturbation rejection, however the most difficult step in designing a fuzzy controller is the fuzzyficaion stage where we have to determine the rules and the shape of membership functions...
Accurate detection of cyber-attacks plays a central role in safeguarding computer networks and information systems. This paper addresses the problem of detecting SYN flood attacks, which are the most popular Denial of Service (DoS) attacks. Here, we compare the detection capacity of three commonly monitoring charts namely, a Shewhart chart, a Cumulative Sum (CUSUM) control chart and exponentially...
This paper presents the stabilization of three-dimensional fractional-order Lü chaotic systems, by means of an adaptive sliding mode based on Lyapunov stability theory. It focuses on an important issue in the research of fractional-order systems that is chaos stabilization. Based on the proposed adaptive sliding mode control method, the states of the fractional-order system have been stabilized; Numerical...
The steganography is the art of hidden; its main aim is to pass unnoticed data in another data. There are many types of data that used in steganography, such as message, image, and video. In this work, we are interested in hiding a message inside an image. Our work focuses on the study of three approaches based on least significant bit (LSB) techniques that mean put the bits of the message in the...
This paper presents an implementation of Doubly Fed Induction Generator (DFIG) based Standalone Wind Energy Conversion System (SWECS). Control algorithms of Rotor Side Converter (RSC) are presented for maintaining voltage and frequency for variable speed DFIG based SWECS. A prototype of this proposed DFIG based SWECS is developed using a DSP (Digital Signal Processor-dSPACE DS1104). The proposed DFIG...
This paper presents a new precise vision to diagnose the eccentricity fault using the motor current signature analysis technique (MCSA). The MCSA method was based on analyzing the FFT of the stator current. But, it has many disadvantages, as operating regimes (non-stationary) or his suffering to distingue the characteristic frequencies of several faults such as short circuit, eccentricity, broken...
Distribution networks reconfiguration is among the main tasks in distribution management system. The networks reconfiguration is determined by opening and closing switches devices. This reconfiguration can be static or dynamic. In static reconfiguration, the loads are assumed to be constant, while in dynamic reconfiguration loads are assumed to vary according to time. In this work, a dynamic reconfiguration...
This paper presents a simulation and experimental study on power sharing between batteries and supercapacitors. Filters are used as a frequency splitter to share the power demanded by the load between the battery and the supercapacitor according to their dynamics. Experimental tests were carried out on a test bench to validate the proposed simulation.
Impact of electric transformer impedance on squirrel-cage induction motor (SCIM) behavior, namely torque peaks and loss of speed, during symmetrical and unsymmetrical voltage sags is qualitatively analyzed on three-phase SCIM in this paper. These effects depend on several variables like sag type, duration and depth. The presence of transformer impedance always results in torque peaks higher than when...
The paper presents a new multi-controllers approach with H∝ control applied to control a manipulator robot wrist (Staubli RX-90). A brief description of process and linear mathematical modeling of the process. Principle of multi-controllers approach of control is briefly presented. Our new proposals concerning the type of the controllers used in the multi-controller approach of control and which are...
In this paper, we present a new Adaptive Local Search approach (ALS) and its implementation for the NP hard Timetable Scheduling Problem. This approach uses graph heuristics to generate the initial solution and the Aspiration criterion with Random moves strategies to improve a guided local search procedure for the search process. Experimental results on a collection of data sets from the popular Carter's...
The block oriented structure such as Hammerstein, Wiener, etc… became very popular for the non-linear system modelling due to its simplicity and parsimony. In this paper, fractional hammerstein system is considered; it consists of a static non-linear block followed by a fractional linear dynamical block. The particle swarm optimisation is used to estimate the system parameters as well as the fractional...
Renewable Energies (RE) are considered as an important alternative sources of energy for the generation of electricity such as hydrogen and photovoltaic energies. To ensure an efficient photovoltaic energy conversion several Maximum Power Point Tracking (MPPT) algorithms have been developed to incite the PV field to deliver maximum power. This paper presents a comprehensive comparative study of two...
In this paper we have described a new design algorithm for the whole set of latent-structure assignment via the approaches of matrix polynomial placement with output noise rejection for a Quadruple tank process, of course the mathematical dynamic model of the process is obtained by MIMO (Simplified Refined Instrumental Variable) SRIV and/or MIMO (Linear Multi Stage Auto Regressive Moving Average with...
