The control of 2D linear systems with parameters uncertainties will be studied here, using an H∞ approach and linear matrix inequalities LMI techniques. Robust monotonically convergence will be demonstrated with designing robust iterative learning control ILC. D type iterative controller will be presented by decreasing the errors from iteration to iteration until becomes zero. The robust stability of the 2D systems will be also demonstrated in the next of this paper. An illustrative example is presented to show the applicability of the proposed results.

This paper describes the development of a strategy to optimally tune constrained predictive controller of Multi Inputs Multi Outputs Nonlinear system with T-S fuzzy modeling approach. The proposed method consists of using T-S fuzzy modeling to determine process model. The intelligent algorithms Particle Swam Optimization is applied to provide the controls action by solving nonlinear optimization problems which is function of the future prediction outputs and the future inputs. The performance of this strategy is evaluated through its application to Quadruple-Tank Process.

Despite the well-known efficiency of the conventional MCSA (Motor Current Signature Analysis) technique for detecting the occurrence of load torque ripples by monitoring of sidebands close to the supply frequency, many other rotor faults produce this same spectral signature leading the user to be faced with a confusing situation. The aim of this paper is to propose an alternative that could overcome this major drawback. The experimental results conducted on a laboratory test-rig have revealed that the spectral signature of the emf induced at the terminals of a search coil placed near the motor frame may provide relevant information of diagnosis purpose, when the load torque oscillates at low frequencies.

This paper focuses on the development of a robust Fractional Order Extremum-Seeking (FOES) scheme for controlling the ABS of vehicle motion system by continuously adjusting the brake torque. Extremum Seeking (ES) known for its properties to seek the maximum of unknown function and Fractional Order (FO) control for its robustness in the presence of parameter variations and the disturbances are employed to control the wheel slip rate in emergency braking maneuver. The aim of an ABS is to minimize brake distance while steer ability is retained even under hard braking, to understand the fundamental physical effect, which leads to wheel blocking during braking. Simulations under various road conditions are performed to demonstrate the effectiveness of the proposed control scheme.

The paper presents a comparison of performances and characteristics of a Self Scheduled linear parameter varying (LPV) Flux Observer and observation algorithms based on Kalman Filter for induction motor rotor flux estimation, inserted in a field oriented control scheme. The construction of the considered algorithms is described in detail, and the different design issues are explained. For true comparison the same measurements are assumed available to both deterministic and stochastic estimators, and the same controller parameters are used in simulation. The performances of the estimators are compared either in terms of observation errors during transient and steady state operations either in terms of robustness face to variations of motor parameters.

This paper deals with fuzzy modeling of nonlinear systems affected by bounded uncertainties. The proposed model is composed of two parts: a linear uncertain part and a nonlinear part. The linear uncertain part is obtained by system linearization around some operating points. Nonlinear part parameters are estimated through the use of the descent gradient method. Finally, two examples are treated to illustrate the effectiveness of the proposed modeling method.

This work focuses on energy management as one of the main parts of energy harvesting systems. Energy management circuits are classified into three categories depending on their complexity, namely: low - medium - and high complexity level circuits. Thereafter, the idea is to build an energy management solution and to integrate it in two different circuits: medium complexity level circuit and high complexity level circuit. Comparisons based on power consumption demonstrate that the use of microcontroller and high complexity energy management circuits in some types of applications is not convenient and represents a loose of energy.

This paper investigates the problem of trajectory tracking for nonholonomic wheels mobile robots. Constraints nonholonomic that arise in this type of robot, and the uncertainties in the system parameters and disturbances present difficulties and problems in trajectory tracking of mobile wheeled robots, which limits the region of application. To solve this problem, a nonlinear controller based on Lyapunov theory associated with sliding mode control is developed. The simulation results show the tracking performance of the proposed control.

In this work, we are interested in the problems of energy conservation and life expectancy of knots; because, they are not refillable by micro-piles. To solve the problem of limitation of the network regarding energy resources, our approach is based on a combination between several existing mechanisms of energy saving by addressing more particularly on the data routing. The existing routing protocol ZRP cannot resist in large scale (because it isn't an adapted protocol for WSN). To overcome this limit, our approach consists in improving this protocol with the aim of having the best answers for the requirements of WSN by the introduction of the hierarchical organization based on the crossing between different layers, to obtain the proposed protocol H-ZRP. We have been used NS2 for simulation. Our proposal approach offered the best performances and more reliability than at the loss packets rate, deadline from start to finish, and transmission rate.

This paper proposes an improvement of an existing algebraic method for estimating the domain of asymptotic stability of nonlinear discrete systems. The studied approach is essentially based on a polynomial description of nonlinear dynamical process and on analytic and iterative procedure of stability radius determination of nonlinear discrete systems.
