Abstract
In this paper, a class of linear systems affected by both
parameter variations and additive disturbances is con-
sidered. The problem of designing a set-valued state
observer, which estimates a region containing the real
state for each time being, is investigated. The tech-
niques for designing the observer are based on posi-
tive invariant set theory. By constructing a set-induced
Lyapunov function, it is shown that the estimation er-
ror exponentially converges to a given compact set with
an assigned rate of convergence.
