Switched descriptor systems characterized by a repetitive finite sequence of modes can exhibit state discontinuities at the switching time instants. The amplitudes these depend on consistency projectors modes. A switched ordinary differential equations model whose continuous evolution approximates original system is proposed. Sufficient conditions based linear matrix inequalities ensure that ap...

A general upper bound for topological entropy of switched nonlinear systems is constructed, using an asymptotic average limits the matrix measures Jacobian matrices strongly persistent individual modes, weighted by their active rates. lower constructed as well, a similar traces these matrices. In case interconnected structure, readily applied to derive bounds that depend only on “network-level”...

This article proposes a new diagnosis approach extended to switched mechatronic systems. The best tools of modeling and supervision, notably bond graph observer, are used move towards high reliable fault detection isolation approach. Researchers have always divided the hybrid observer into two blocks: location that identifies current mode continuous detects faults. Applying same logic system wi...

|Abstract: High-Technological solutions of today are characterized by complex dynamical models. A lot of these models have inherent hybrid/switching structure. Hybrid/switched systems are powerful models for distributed embedded systems design where discrete controls are applied to continuous processes. Hybrid systems are also an important modeling class for nonlinear systems because a wide var...

This paper is concerned with the H∞ control problem for a class of non-minimum phase cascade switched nonlinear systems. The system under consideration is composed of two cascade-connected parts which are also switched systems. Sufficient conditions under which the H∞ control problem is solvable under an arbitrary switching law are presented. The Common Lyapunov function and the switched state ...

A summarized study of the current state-of-the-art of the controlled intelligent systems based on the synergy of the potential of fuzzy logic in Takagy-Sugeno fuzzy systems with the structural flexibility and sustainability of switched nonlinear dynamic systems. In particular, following some of the fundamental theorems on quadratic stability of general nonlinear dynamic systems, due to Zhao and...

The observability of deterministic, discrete-time, switched, linear systems is considered. Depending on whether or not the modes are observed, and on whether the continuous state or the mode sequence is to be recovered, several observability concepts are defined, characterized through linear algebraic tests, and their decidability assessed.
