The Kalman filter (KF) has received a huge interest from the industrial electronics community and has played a key role in many engineering fields since the 1970s, ranging, without being exhaustive, trajectory estimation, state and parameter estimation for control or diagnosis, data merging, signal processing, and so on. This paper provides a brief overview of the industrial applications and implementation issues of the KF in six topics of the industrial electronics community, highlighting some relevant reference papers and giving future research trends. © 1982-2012 IEEE.

This paper provides a model and a control of a marine current energy conversion system. The modeled marine current energy conversion system is a 10-kW generating system with a low-speed doubly salient permanent magnet generator of 50 rpm. First, the resource, the turbine, and a dynamic analytical model of the generator are developed. Second, due to variations of marine current speed, which may lead to strong fluctuations in the power extracted by the marine current turbine, control strategies for the marine current energy conversion system at both low and high marine current speeds are analyzed, assessed, and compared. Finally, simulations of the proposed system are carried out, modeled, and simulated on MATLAB/Simulink software. © 2015 IEEE.

Electrical double-layer capacitors (EDLCs) are now widely used as power buffers in energy storage systems, especially for electrical transport applications. Because of their high acquisition costs, their predictive maintenance represents a key issue for the development of electrical traction systems. This paper investigates the diagnosis of EDLCs by a parametric estimation of a dynamic continuous-time model. Indeed, the physical interpretation of their parameters simplifies the supercapacitor diagnosis and prognosis. Due to the complex electrochemical phenomena occurring in EDLC cells, modeling errors are far more important than measurement noise. Therefore, we propose to use the output error minimization techniques and the relative sensitivity functions to evaluate and compare the diagnosis potential of several model structures. This allows the use of some comprehensive comparison criteria without any assumption about the statistical characteristics of the system disturbances. An experimental accelerated aging process of 200 commercial super capacitors (Nichicon, 1F, 20 weeks long aging at 65 .C, 0 and 2.5 V dc polarization) is also performed to make statistics and illustrate the methodology. © 2015 IEEE.

This paper deals with controls of a converter, where two paralleled-inverters are used. One inverter acts as a master unit and the other one acts as a slave unit. Thanks to these controls, an accurate tracking of the references is got and the output voltage ripples are lowered. As the goal is not to expand the system capacity, the slave unit delivers the currents to the load and becomes the power source meanwhile the master unit is in charge of the output voltage regulations. Thus the master unit compensates the ripples of the slave module output currents. In order to understand the proposed strategy, it is necessary to start with the operation of the Phase-Shift Self-Oscillating controllers. Then the operation of the paralleled-inverters is explained and a model of the power circuit is investigated. Simulations and experiments confirm the high performances in terms of ripples rejections. © 2015 EPE Association and IEEE.

The Ocean, which covers two-thirds of the world, captures and stores huge amounts of energy. Several sources of energy can be used. This paper presents a brief review of state of the art on the marine tidal current generation technology. The purposes are as follow: the first part concerns the conversion of marine current energy into mechanical energy, a synthesis of the existing methods of the modeling of the resource and of the marine current turbine are presented. The second part is dedicated to the conversion of the mechanical energy to electrical energy by taking into account the power converters for the control and the grid connection. Some simulation results are briefly shown for each part. © 2012 IEEE.

This paper develops a novel method for optimal design of fractional slot with concentrated windings. The basis of this method is a generalized analytical model of the winding magnetomotive force (MMF) combined with a multiobjective genetic algorithm, which searches the optimal winding parameters that maximize the winding factor and minimize the MMF harmonic content. This technique is applied to optimize the winding layout of the permanent magnet synchronous machine with 12 × n slots/10 × n poles combination ( n is an integer number). The electromagnetic performances of the optimized winding are investigated and compared with conventional winding topology. It is found that the proposed approach allows the emergence of new windings with higher performances. © 2016 IEEE.

Growing concerns about petroleum supplies and air pollution have spurred increased interest and research into hybrid electric vehicles (HEVs). While standard driving cycles are commonly used for the purpose of propulsion chain optimization, the issue of how representative they actually are is questioned. This paper proposes a novel methodology for modeling real-world vehicle missions by considering the stochastic characteristics of the driving pattern and the dependence among the variables of the mission, i.e., vehicle speed, acceleration, and road gradient. The modeling procedure is based on a Markov matrix formulation, and a simulation algorithm is implemented to generate an unlimited number of stochastic mission profiles. Two kinds of mission natures have been modeled and discussed so as to stress the mission impact on the energy consumption according to the propulsion chain sizing. The approach is then validated using the architecture of a series HEV powered by a diesel generator and batteries. The results on fuel consumption are presented, and the benefit of the proposed method over conventional approaches is argued. © 2012 IEEE.

This article elaborates a techno-economic approach that aims to optimize the conversion and energy storage unit chain of the first quick charge plug-in ferry. The choice of supercapacitors is motivated and then compared to other energy storage units for different kind of ferry exploitation. Several models were developed to be coupled with a global techno-economic model considering an exploitation strategy. In the last part, a typical application illustrates the cost reduction compared to the standard sizing approach. © 2015 Elsevier Ltd.

In this paper, safe techno-economic sizing methodology of a standalone photovoltaic system is investigated. It is proposed to size the system on the basis of solar radiation measurements. Then, Markov transition matrices (MTM) are used to simulate stochastic cloud cover sequences. Each sizing is then tested on a large number of scenarios. It is thus possible to use a statistical approach of the sizing results, in particular on the Loss of Power Supply Probability (LPSP), which is highly sensitive to the stochastic nature of cloud cover. A case study (Saint-Martin en Haut, in France) is given to illustrate this methodology. © 2015 Elsevier Ltd.

In this paper a percolation model is used to determinate the electrical conductivity tensor of one layer of carbon fiber composite. For this kind of material, fibers are randomly distributed in the resin. To take into account this distribution a virtual 3-D material model is developed and coupled with a homogenization method to overcome the scale factor problem. The electrical conductivity tensor is then used to simulate the induction heating of a multilayer composite. © 1965-2012 IEEE.
