Robust control invariant set of linear systems with disturbances

In this paper the schemes to compute robust control invariant sets for linear (uncertain) systems are collected, which are not necessary minimal robust control invariant sets. Firstly, the concept of logarithmic norm is resorted to a simply differential functional inequality. Feedback control laws are obtained for both of the two schemes. In the scheme based on the differential functional inequality, the obtained robust control invariant set is a level set of the storage function.
