Abstract :
Practical stabilizability of discrete-time (DT) switched systems is studied in this paper. We first prove a sufficient condition for ¿-practical asymptotic stabilizability of DT switched systems, then we focus on switched affine systems and present an approach to estimating the minimum bound for practical stabilizability. Based on the approach, we present several new sufficient conditions for global ¿-practical asymptotic stabilizability of such systems. Since DT switched affine systems are often derived by sampling continuous-time (CT) switched systems, we finally present some preliminary results on the relationship between CT and DT switched affine systems.
