Interval observer design for estimation and control of time-delay descriptor systems

Abstract: a b s t r a c tThe problem of interval observer design is addressed for a class of descriptor linear systems with time delays. First, an interval observation for any input in the system is provided. Second, the control input is designed together with the observer gains in order to guarantee interval estimation and stabilization simultaneously. Efficiency of the proposed approach is illustrated by numerical experiments with the Leontief delayed model.

“…By induction, if e(0) ≥ 0 and e(0) ≥ 0, then the relations e(t) ≥ 0, e(t) ≥ 0 are preserved for all t ≥ 0 [32]. Therefore, from (13) the inclusion (14) is valid.…”

“…An advantage of interval observer is that it allows many types of uncertainties to be taken into account in the system. The interval observer design techniques have been developed for many types of models: continuous-time [38], [48], [9], discrete-time [16], [39], [21], [40], time-delay [41], [17], [18] and algebraic-differential [19] ones.…”
