First, we propose set-valued estimator algorithm using symmetric boxes to compute rigorous bounds of the system states. The observer gains are calculated using (Formula presented.) norm to attenuate the effects of the uncertainties and to improve the accuracy of the proposed estimator. Second, to obtain tighter state enclosures, zonotopic set computation are developed instead of interval analysis to design a new set-valued state estimation algorithm. The performances of the proposed state estimation approaches are highlighted on different illustrative examples. © 2024 John Wiley & Sons Ltd. |
