Controlling Uncertain Systems within a Subset of the State Space

Abstract

In previous work, stabilizing controllers were developed for uncertain systems whose state space is Rn. Here, we present stabilizing controllers for uncertain systems whose state space is some open subset of Rn or for which it is desired to keep all state motions within some open subset of Rn. The controllers, whose construction is based on Lyapunov theory, are, in general, nonlinear. Their use is illustrated by an example.
