A Bond graph switching observer for switching linear systems

In this paper, we propose a switching Luenberger observer design in order to reconstruct the continuous part of switching linear systems modelled by bond graph. The proposed method allows showing that the bond graph approach can be used as a tool for modelling, for structural analysis and for formal calculus. In this method only one bond graph model of the observer is used to calculate the gain matrices. The calculus of the observer gain is based on the pole placement techniques for linear systems modelled by bond graph proposed by Rahmani et al.(1994). On the other hand, the choice of the Lyapunov function rather difficult with conventional methods is easier.
