DOI: 10.1007/s00034-019-01122-0
Abstract: In this study, a finite-time interval observers’ design method is developed for switched systems suffering from disturbance. First, the interval observer frames for the systems are constructed. Then, sufficient conditions are derived to guarantee that… read more here.

DOI: 10.1016/j.ifacol.2020.12.592
Abstract: Abstract This paper discusses some issues related with the design of a bank of interval observers for uncertain switched systems, in which several sources of uncertainty are considered: parametric uncertainties, unknown disturbances, measurement noise, and… read more here.

DOI: 10.1109/access.2021.3139244
Abstract: 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 uncertainties. The interval observers depend on the design of two… read more here.

DOI: 10.1109/lcsys.2022.3220502
Abstract: We provide a new input-to-state stabilizing event-triggered feedback design for linear systems with unknown input delays, unknown measurement delays, and unknown additive disturbances. Our trigger times are computed using only the matrices defining the system… read more here.

DOI: 10.1109/tsmc.2018.2790975
Abstract: This paper designs interval observers for polynomial fuzzy singular systems, in which the external disturbances and unknown parameters are included in the systems. The polynomial fuzzy modelings are proposed, which are more practical than Takagi–Sugeno… read more here.
