The major interest is to apply these results in an industrial or technical context, where some of the communications are strongly time-constrained. In this paper, we have chosen the network calculus theory, because it enables a good representation of the exchanges between the equipment which are connected to the network, and also to determine the maximum end to end delays. Previous models presented are improved in order to take into account the implementation of a classification of service (CoS) mechanism which enables to define priorities for the messages regarding the time constraints they have to respect This paper describes a new model of a IEEE 802.1p switch. It also presents the analytical formulas which upper bound the maximum time for crossing such a switch, and an algorithm to determine the maximum end to end delays of the time-critical messages over the whole network. A typical application shows the interest of this approach","PeriodicalId":111199,"journal":{"name":"2004 IEEE International Conference on Robotics and Automation (IEEE Cat.

Design of the TITO controllers that are included into the library is based on polynomial methods. The controllers are based on various configurations of the closed loop system.

With the introduction of new mesh generation algorithm and NDM (nested dissection method), our FEM package can guarantee the shorter computational time than MATLAB PDE Toolbox. In addition, using the advanced electromagnetics library of CEMTool FEM package, we can analyze the practical problems such as the motor field analysis.

We use a technique that combines dynamic programming and informed search. The control sequence generated by our synthesis procedure is guaranteed to meet safety requirements.

This minimization involves the closed-loop eigenvalues as well as a group of parameter vectors when the closed-loop eigenvalues are not prescribed.
