This note constructs a functional observer for second‐order linear time‐varying (SOLTV)
systems under framework of second‐order systems. Based on the assumption that the …

This paper designs an observer‐based feedback controller for quasi‐linear systems when
the entire state vector is unavailable for measurement. First, based on the solution of a type …

This paper investigates the problem of the functional interval observer design for linear time-
varying (LTV) systems with additive disturbances in both input and output channels. First …

This article investigates the state interval observation problem for a class of continuous and
discrete‐time linear time‐varying (LTV) systems with bounded uncertainties separately. First …

Identification of parameters involved in the linear response model with high precision is a
highly cost-effective, as well as a challenging task, in developing a suitable model for the …

X+ AT∗ NY− 1∗ NA= I, Y+ BT∗ NX− 1∗ NB= I, which is the generalized form of a system of
nonlinear matrix equations studied in the literature, occurs in many applications such as …

This paper investigates the design of reduced-order functional observer for linear time-
invariant systems (LTI) with time-varying delay. Firstly, the sufficient condition for the …

This article investigates the issue of robust control based on interval observers for
continuous-time linear time-invariant (LTI) systems with input saturation and disturbances …

This letter presents a novel approach to designing quantitative interval observers for linear
systems with time-varying delays and disturbances. A new type of interval observer is …

This paper deals with the problem of robust state estimation for linear discrete-time switched
systems with uncertainties. In order to reduce both complexity and observer order, the …
