摘要：AbstractThe scope of this paper is the design of interval observers for linear parameter-varying systems subject to input and output uncertainties. To this, two coupled dynamical systems are designed which compute an upper bound and a lower bound of the state which enclose the real value with a bounded interval width. Besides of a full-order interval observer, a reduced-order interval observer is proposed to reduce the computational effort. In addition to sufficient conditions and the mathematical description of the interval observers, an optimization-based design procedure for their practical application is presented. The performance of the interval observers is shown by the guaranteed state estimation of an induction machine.
