The presentation focuses on stability analysis based on copositive Lyapunov functions (CLFs) for arbitrary switching positive linear systems with discrete-time or continuous-time dynamics. The techniques for constructing linear, max-type or quadratic-diagonal CLFs rely on the properties of row and column representatives associated with the set of matrices corresponding to all the subsystems. Using comparison theory, these techniques may be extended to arbitrary switching linear systems which are not necessarily positive.

Mihaela Matcovschi received M.Sc. degree in Mathematics (1986) from the "Alexandru Ioan Cuza" University of Iasi, and M.Eng. degree in Automatic Control (1999) and Ph.D. in Industrial Engineering (2001) from the "Gheorghe Asachi" Technical University of Iasi, Romania. Since 2008 she is a Professor at the Department of Automatic Control and Applied Informatics from the "Gheorghe Asachi" Technical University of Iasi. Her research interests in the field of Systems Engineering include qualitative analysis of dynamic systems based on flow-invariance theory, and also modelling, simulation and analysis of discrete event dynamic systems based on Petri nets theory and queueing systems.
