This paper considers the optimal control of a class of stochastic continuous-time linear systems with sudden changes in parameters. The jumps of parameters from one value to another are described by a finite-state Markov chain. When the cost-function is quadratic, the optimal Jump Linear Quadratic control involves a set of coupled Riccati equations. The asymptotic behaviour of this set is studied...
Resume La présence de retards sur l'état ou sur la commande est fréquente dans les processus réels mettant en jeu des phénomènes de transport. L'application de techniques dérivées des travaux de Kalman conduisent certes à des solutions en boucle fermée mais au prix de calculs très complexes, ce qui restreint de fait leur application à des processus de faible dimension. Récemment les auteurs...
This paper presents a new image based hybrid algorithm for the maneuvering target tracking problem. An optimal filter for the mode of the target that fully exploits the imaging capacity of electro-optical sensors (EO) is introduced first. The second part presents the architecture of the hybrid imaging filter (HIF). The efficiency of the HIF leads to a significant improvement of the tracking performance...
The filtering problem of systems with Markovian jump parameters is considered. Since computing the optimal solution of such problems remains most often untractable. approximate solutions are usually sought. Here we present such an approximation, but defined in a rigourous sense by extending some previous results obtained by Di Masi and Runggaldier [Di 81] on diffusion processes.
In this work, different configurations of IT-SOFC complete cells: ITM porous support / Ni-YSZ / YSZ / La2NiO4 with and without GDC protective layers were realized by two different surface treatment processes. The porous anode layer was deposited by Atmospheric Plasma Spraying (APS). The thin, dense and columnar electrolyte layer was deposited by reactive magnetron sputtering (PVD) with PEM system...

In this contribution, we investigate the possibility of eliminating the crowbar circuit which is normally used to protect the auxiliary railway supply system in case of a catenary transient overvoltage. The idea is to act at the control level by suspending the operation of the auxiliary inverter when the input voltage reaches some given threshold. Experimental results are firstly presented for an...
The previous parts of this series of papers was dedicated to current transformers (CTs) designed and tested according to ANSI standards. The determination and specification of CTs for applications based on North American practices was also discussed. This part presents many of the same themes as the previous parts including test results, but from the viewpoint of the International Electrotechnical...
