Both States and Unknown Inputs Simultaneous Estimation for Fractional-Order Linear Systems

C Peng, L Ren, Z Zhao - Circuits, Systems, and Signal Processing, 2024 - Springer
This article is devoted to estimating simultaneously both the states and the inputs of linear
time-invariant fractional-order systems (LTI-FOSs) with the order 0< α< 2. Firstly, a necessary …

An iterative LMI-based reduced-order observer design for fractional-order chaos synchronization

M Pourgholi, EA Boroujeni - Circuits, Systems, and Signal Processing, 2016 - Springer
In this paper, attempts are made to design a reduced-order observer for a nonlinear
Lipschitz class of fractional-order systems. It is assumed that nonlinear terms not only …
