Stabilization of linear systems subject to control constraints via minimal-order observers

The stabilization of linear constrained discrete-time systems via minimal-order observer is addressed. The problem of local stabilization is considered. From a state feedback control law guaranteeing the positive invariance and the asymptotic stability of a certain domain D/sub 1/, the influence of the estimation error is analyzed in terms of the linear control trajectory. The observer design considering the minimization of the influence of the estimation error is also studied.
