An interval multiobserver is proposed in this paper for dealing with nonlinear systems subject to disturbances and noises. The stability of the systems and the cooperativity of observation errors are studied using LMIs, and an augmented system is introduced for tracking control. A numerical example is provided to demonstrate the effectiveness of the interval multiobserver in state estimation and control strategy.
In this paper, an interval multiobserver is designed for nonlinear systems subject to unknown but bounded disturbances and measurement noises. The behavior of discrete nonlinear systems is described by an uncoupled multimodel. Linear Matrix Inequalities (LMIs) are formulated to study the stability of the proposed systems and to ensure the cooperativity dynamic of the observation errors. An augmented system is introduced to apply a tracking control where the control gains are obtained by pole placement. Finally, a numerical example is proposed to verify the efficiency of the interval multiobserver in state estimation and to prove the performance of the control strategy to follow the desired trajectory.
