Observers of fractional linear continuous-time systems [PDF]
Archives of Control Sciences, 2022 The concepts of full-order and reduced-order observers are extended to the fractional linear continuous-time systems. Necessary and sufficient conditions for the existence of the observers for fractional linear systems are established.

Observers for the quasi-linear systems
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2010 The problem of quasi-linear systems stabilization in the case of incomplete feedback is considered. While synthesising a stabilizing control, estimation of a current state vector-is applied. To design this estimation, observers are constructed.

Generalized observer design of index one for descriptor systems with unknown inputs [PDF]
Archives of Control Sciences, 2023 Generalized observers are proposed to relax the existing conditions required to design Luenberger observers for rectangular linear descriptor systems with unknown inputs. The current work is focused on designing index one generalized observers, which can

Smooth Non Linear High Gain Observers for a Class of Dynamical Systems
IEEE Access, 2022 High-gain observers are powerful tools for estimating the state of nonlinear systems. However, their design poses several challenges due to the need of dealing with phenomena such as peaking and chattering.
