New results on practical stabilization and practical reachability of switched systems

The present paper has two main contributions. First, we report new sufficient conditions for practical stabilizability of switched systems. Such conditions are geometrically more appealing and easier to check than conditions proposed in our previous papers. The conditions are applicable to practical stabilizability problems over infinite or finite time intervals. Second, we study the practical reachability problems in the light of our practical stabilization results. Sufficient conditions for practical reachability are presented.
