In this paper we study the distributed mean-variance paradigm with linear state dynamics of mean-field type in discrete time and several control inputs. The goal is to reduce the variance and the mean of the state in a fully distributed manner. We formulate and explicit solve the problem using recent development of mean-field-type games. We show that there is unique best response strategy to the mean of the state and provide a simple sufficient condition of existence and uniqueness of mean-field equilibrium. We also provide a closed-form expression of the global optimum as a state-and-mean-field feedback strategy.

In this era of latest technologies and innovation, energy consumption is a key feature which requires special attention while implementation of a system. One of such evolving technologies is Wireless sensor networks (WSN). We have seen a huge amount of progress in the research has been going on in the field of WSN recently. The improvement in home automation technology and other luxury systems has made comfort a key factor in today's life. In this paper we have shown the integration of a comfort cooling system with the cloud. Iris motes are used for monitoring and controlling the room temperature. The system uses Low-Energy Adaptive Clustering Hierarchy (LEACH) algorithm to make the system energy efficient. The iris motes used to control the temperature are connected to a stepper motor installed in the air outlet. The efficiency of the system is compared with that of Ad-Hoc Distance Vector (AODV) routing protocol. This system was tested with an Earth Air Tunnel (EAT). This integrated system shows the versatile nature of WSN keeping in mind the low power consumption and reliable data transfer. This tested system provides a pollution free environment as it uses Earth's geothermal energy for cooling and not CFC based cooling systems like that of Air Conditioners hence keeping the environment clean and green. The data accumulated is uploaded directly in the cloud so that we can monitor from any location in the world and in order to show this we have designed an android application which controls the system.

This paper presents a study on the Tunisian electrical network with multilateral mixed HVAC and HVDC interconnections. First, a generic average model of the HVDC line is developed. The parameters of the HVDC link power modulation controller are determined and tuned using the Graphical Identification method of "STRECJ". The multilateral ties of the system are studied via different study cases: single, bilateral and trilateral interconnections in DC and AC configurations. In particular, a parallel AC-DC interconnection between Tunisia and Libya is simulated. A special emphasis is given to an HVDC link to the Italian transmission grid. The results confirm the contribution of the HVDC transmission links in improving the Tunisian network stability.

In this paper a new capacitor-less LED drive is proposed. The design is based on the utilization of the internal capacitance of the LED to replace the smoothing capacitor. LED lighting systems usually have many LEDs for better illumination that can reach multiple tens of LEDs. Such configuration can be utilized to enlarge the total internal capacitance and hence minimize the output ripple. In addition, the switching frequency is selected such that minimum ripple appears at the output. The functionality of the proposed design is confirmed experimentally and the efficiency of the drive is 85% at full load.

In windsurfing, pumping is a reference technique for improving sailing performance and speed. This technique depends on both navigation and athlete physical conditions. For coaches and athletes, the masthead trajectory during pumping is a good indicator to identify the technique being used. In this way, a method based on geometric model used in robotics is proposed to track masthead position using inertial sensors. The proposed mathematical model was validated by simulation; to study the performance of the proposed inertial-based tracking system, preliminary measurements have been carried out indoor on a commercial mast foot. The accuracy of the angles deduced from the inertial sensors measurements was investigated by comparison between the mast foot attitude obtained from nertial sensors' data and from a commercial video-based tracking system taken as reference. A maximum mean error below 10% has been found and the recreated top mast foot trajectory from inertial sensors showed a good similarity with that obtained from the video-based tracking system.

In this study, the cell behavior in a photovoltaic (PV) module will be investigated by using two electrical characteristics models of mono-crystalline solar cells: (i) the single diode model, and (ii) the double diode model. Several of the used models parameters are not provided by the manufacturer. The identification of internal parameters of the PV cell is performed by means of research algorithms using data provided by the manufacturer datasheet. Moreover, influences and effects of temperature and irradiance level variation are studied then compared for the proposed models. Simulations Results are compared to those provided by JAC M5SF-2 cell's datasheet. Then, the accuracies of proposed models are validated against experimental tests under the real operating conditions. Results show an acceptable and close similarity with the data issued by the manufacturer data. Identification algorithms, based on the manufacturer data, can thus, be very useful for researchers or engineers to define quickly and easily the internal parameters of any solar cell.

This note focuses on state observer design for a general class of nonlinear discrete-time systems. The main contribution lies in the use of the differential mean value theorem (DMVT) to transform the nonlinear error dynamics into a linear parameter varying (LPV) system. This has the advantage of introducing a general condition on the non linear functions. An extension to H∞ filtering design is obtained for systems with linear and nonlinear outputs. LMI conditions are presented to ensure asymptotic convergence. Then performances and accuracy of the results are illustrated through simulation examples.

This paper proposed a new frequency changer, which can be regarded as a current source cycloconverter. Frequency changing is achieved by mixing two or more amplitude modulated current waves at supply frequency using power transistors. By appropriate selection of the modulation indices and phase shift between the supply voltages, the supply frequency component can be entirely suppressed. The harmonics content of the resulting current wave is found to be very low. This converter solves the problems and severe restrictions associated with the ordinary full-cycle synchronous AM modulation when applied to three-phase and multi-phase systems. The process of conversion involves only natural commutation.

This paper is dedicated to the sensor fault tolerant control scheme for autonomous vehicle driving. The nonlinear lateral vehicle model is described by the fuzzy Takagi-Sugeno (TS) model. The contributions aspects of this work consist of the development of a descriptor observer to estimate the state system and faults by ensuring robustness against external disturbances. The gains of this observer are obtained by solving the LMI constraints, which are developed using a L2 gain technique and H∞ criterion. Indeed, the proposed fault tolerant control strategy is justified by its ability to maintain an acceptable performance in the presence of the sensor failure. Simulation results are addressed to demonstrate the capability of this fault tolerant control to counteract the effect of the sensor fault.
