This paper deals with a Permanent Magnet Synchronous Generator (PMSG) driven by a Marine Current Turbine (MCT) through a PWM power rectifier and used for isolated sites. The generator model is established in the synchronous rotating dq reference frame. The control of the speed, the d-axis current, and the q-axis current is achieved using PI correctors. Robustness and performance of the considered system are evaluated in healthy and faulty conditions. The faulty mode deals with the study of single and multiple open-switch damages appearing in the PWM power rectifier. Simulations are carried-out to highlight the proposed PMSG-based MCT performance in both cases.

This paper will present the new mobile network generation named 4G as empowered by an innovative architecture called CRAN (Cloud Radio Access Network). This will guarantee best coverage and provide higher throughput. Indeed, we will discuss the performance obtained in simulation based on femto cells and OFDMA access technology use. In addition, we will underline the benefits of an 8×8 MIMO configuration compared to other configurations having previously operated.

In this paper, multi-vehicle and multi-depots pickup and delivery problem with time windows (m-MDPDPTW) is presented as a multi-objective problem. The main contribution is to develop a new encoding and structure algorithm for multicriteria optimization approach using genetic algorithm with Pareto dominance method and elitist selection strategy for replacement. In our problem each request has to be transported by one of the vehicles between paired pickup and delivery locations. Such that, the depot does not contain the goods. We has assumed that all vehicles have the same capacity and each one start and finish route at the same depot. A set of satisfying solutions is given representing the shortest, quickest or cheapest set of routes assigned to a fleet of vehicles which satisfies all customer demand without contravening any of the instance specific constraints (precedence, capacity and time window constraints). These optimal solutions minimize total travel distance, total tardiness time and vehicles number.

The standard sliding mode control (SMC) lads, generally, to the appearing of an undesirable chattering phenomenon to solve this problem we develop a novel approach of higher order sliding mode control (HOSMC). The proposed procedure provides an exponential stability on the sliding surface and guarantees the robustness against uncertainties and external matched disturbances. In this paper, and to show the good performances of the new design scheme we present a comparative study between three well known techniques of HOSMC in literature with our approach. Numerical simulations are developed to show the effectiveness of the proposed approach.

In this paper, one aims at addressing the adaptive observer design for a class of multivariable nonlinear systems with Lipschitz nonlinearities. Two adaptive observers have been derived using two different approaches issued from an overview of the available adaptive observer design literature. The first one is a natural extension of a recently proposed adaptive observer for single output systems, while the second one has been derived bearing in mind the fact that an adaptive observer can be derived using a high gain state observer design approach based on an augmented system model accounting for the unknown parameter dynamics. Both observers are shown to be equivalent in the sens that they are governed by the same equations and the underlying exponential convergences of state observation and parameter estimation errors are insured under the the same persistent excitation condition.

The purpose of this paper is to design a nonlinear PID controller for trajectory tracking of a manipulator robot. The objective is to develop a PID controller having high performances for the controllability and the stability of the manipulator. Moreover, the controller should be easy to implement. In a first step a PID plus a feedforward controller has been developed and implemented on a SCARA robot. In the second step and in order to increase performances of the developed control law, an improving version has been developed by adopting nonlinear gains. Simulation results show the effectiveness of the control law in particular in the presence of variable gains.

This paper deals with the control of the continuous Takagi Sugeno (TS) fuzzy models using discrete control approach. This approach is structured as follows: first, a discrete model is obtained from the discretization of the continuous TS fuzzy model. In this case, the Euler discretization is used for order of approximation superior to one. Second the gains of a non PDC control law ensuring the stabilization of the discrete model are determined. Third by keeping the values of the gains, we check by simulation the stability of the continuous TS fuzzy models through the zero order hold. In this case, the effect of the discretization step on the continuous TS fuzzy models stability results is studied. Simulation example illustrates the effectiveness of this approach.

Nonlinear control laws become the most important strategies to control electropneumatic actuator. To get high accuracy and performance, we need the knowledge of all state variables. This paper focus on the design of high gain observer which estimates the unmeasured states (velocity and pressure in chamber N) from the measurements of the position and pressure in chamber P. Simulations results are presented to test the effectiveness of our high gain observer which is applied to sliding mode controller in order to control tracking position and pressure.

A heuristic strategy is presented and evaluated to operate desalination plants designed for variable power availability. This control strategy is based on two consecutive steps: first developing a prioritized list of units of the water plant based on the current state of the plant and the expected water demand, and then distributing the available energy among those units following the prioritized list. The proposed strategy is evaluated on a case study: a desalination plant designed for production of demineralized water powered by a combination of wind and wave energy. Simulation results show the correct operation of the plant under this control.

This paper is dedicated to an analytical modeling of multi-links microrobot design, and to study the effects of their passive links on the microrobot performances. Also, in order to show the influence of the passive links on the device performance, the impact of the number and shape of passive links on the device behavior is presented. In this context, five natures of tails are presented and investigated to obtain the best performance, which can be provided by the microrobot. However, the results show that the microrobot with an odd number of links has higher performance in comparison with that which has a pair number of links configuration. Moreover, the obtained results show that the electromechanical performance is improved when the number of the passive links is augmented in the case of the microrobot with an odd number configuration.
