This brief deals with the interval observer design for a class of discrete-time switched systems. In order to reduce constraints conditions and improve accuracy estimation, zonotope method is used estimate bounds system states. First, an H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> constructed discretetime systems sufficient are derived guarantee existence observer. Then, employed states based on designed Finally, numerical example...

This article investigates functional interval observer based estimation methods for discrete-time switched descriptor systems with disturbances.

To avoid wrapping effect brought by...

When designing interval observers for switched systems, simplicity, it is always assumed that the switching signal of synchronised with one subsystems. However, in fact, they are asynchronous most cases. In this study, observer design problem discrete‐time systems law investigated. At first, a robust designed based on theory. Then, order to reduce conservatism conditions and improve performance observer, zonotope method applied estimate bounds system state. Finally, two examples provided...

In this paper, the coordinated control problem of deformation and flight for morphing aircraft (MA) is studied by using meta-learning (ML) coupled state-dependent Riccati equations (CSDREs). Our method built on two principal observations that dynamic models MA under varying conditions share a condition independent representation function specific part lies in set linear coefficients. To end, domain adversarially invariant (DAIML) employed to learn shared with offline data. Based learned...

Abstract This paper further explores the challenge of spacecraft interception games under incomplete information. The pursued can change multiple evasive strategies, posing a pursuit problem for interceptor that involves adapting to these changing strategies. A combination interacting model approach and zonotopic H ∞ observer is proposed estimate target’s unknown strategies are then updated based on estimated simulation given comparison show their effectiveness.

This paper focuses on the research interval estimate method for discrete-time linear time-invariant switched systems. When real-time state of system is estimated, it necessary to eliminate influence external interference estimation results and consider problem switching modes. For these reasons, H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> observer design combined with reachability analysis. First, we need a so as reduce impact...

This paper deals with functional interval observer design for discrete-time switched systems under stealthy deception attacks. First, the boundaries of attack are obtained by designing observers. Then a two-step method to observers zonotope is presented. For first step, an H∞ presented and as second applied obtain states. An illustrative example provided in last section demonstrates effectiveness proposed method.
