Abstract

The following paper proposes a novel Multiple Models Method for observer design to solve the problem of state and parameter estimation of uncertain nonlinear time-varying parameters systems with unknown but bounded disturbance. Classically speaking, an interval observer is a special class of observers that generates a bounded interval vector for the real state vector in a guaranteed way under the assumption that the uncertainties are unknown but bounded; it gives an upper and lower estimate for the system states at each time instant (determining a certain interval for the estimated state variations). Several approaches have been developed and adapted to different kinds of models (linear, nonlinear, fuzzy, etc.). However, in the proposed approach, the objective is not to design an interval observer, but rather a classical Luemberger observer, based on an interval multiple model of the nonlinear system model. The novelty introduced in the paper is about proposing a new interval Multiple Models representation of the uncertain nonlinear system. The observer’s gains are developed based on the Lyapunov stability theory proving that the state and parameter estimation errors are stable and converge to an origin-centred ball of a given radius to be minimized. The design conditions are formulated into linear matrix inequalities constraints, which can be efficiently solved. A numerical example is given to illustrate the design and validate the performance of the interval observers.
