In this paper, an output feedback-based active fault tolerant control (FTC) scheme is
proposed for an unstable three degree-of-freedom (3-DOF) helicopter equipped only with …

Based on the theory of positive systems, the goal of interval observers is to compute sets of
admissible values of the state vector at each instant of time for systems subject to bounded …

This paper deals with unknown input interval observer synthesis for discrete-time switched
systems. First, a decomposition leading to obtain a subsystem not affected by the unknown …

In this article, we present an active fault tolerant control scheme based on fault detection and
isolation (FDI) for a class of uncertain systems subject to sensor faults. The FDI unit consists …

In this article, a novel unknown input interval observer (UIIO) is proposed for systems not
satisfying the relative degree condition. In interval estimation, estimation errors are required …

Set-valued algorithms are designed in this work to compute rigorous bounds of the unknown
inputs of uncertain discrete-time linear systems. First, based on the classical full-order and …

This paper focuses on designing a state estimator for a discrete-time SEIR epidemic model
of an influenza-like illness. It is assumed that only sets of admissible values are known for …

In this work state estimation for unknown input discrete-time linear systems is tackled in a
bounded error context. First, under the boundedness assumption on both process and …

In this paper, we investigate the interval observer problem for a class of discrete-time
nonlinear systems, in absence or presence of external disturbances and parametric …

This paper designs an interval estimator for a fourth-order nonlinear susceptible-exposed-
infected-recovered (SEIR) model with disturbances using noisy counts of susceptible people …
