Abstract
In this paper, a necessary and sufficient condition for well-posedness is presented using the inclusion condition of uncertainty, and a set of all the systems corresponding to the uncertainty with which a closed-loop system is well-posed is given. Furthermore, we analyze the topology of the set of systems based on the well-posedness property. We give the number of connected components in the set of uncertainty in the cases of complex matrix uncertainty and 2×2 real matrix uncertainty
