This paper proposes an improvement on observer design of discrete-time fuzzy systems
based on an alterable weights method. Different from the recent result, a more effective …

This paper deals with more relaxed designs of discrete-time Takagi-Sugeno fuzzy-model-
based observers via two effective technical measures. Different from previous methods of …

This paper generalizes recent results on multi-instant observer design for discrete-time
Takagi-Sugeno fuzzy systems through a valid ranking-based switching approach. The …

The problem of observer-based state estimation of discrete-time fuzzy systems is
investigated by constructing a joint switching mechanism for adjacent instants. Thanks to the …

This article develops a unified framework to design fuzzy-model-based observers of general
nonlinear systems for both discrete-time and continuous-time cases. This observer problem …

This paper is concerned with the design of observer for discrete-time nonlinear systems in
the Takagi-Sugeno (TS) fuzzy form. Under the framework of multi-instant homogenous …

This paper presents a sum-of-squares (SOS) approach to polynomial fuzzy observer
designs for three classes of polynomial fuzzy systems. The proposed SOS-based framework …

This letter investigates the design of unknown input (UI) observers for a large class of
nonlinear systems using Takagi-Sugeno (TS) fuzzy modeling. To avoid the well-known issue …

This paper studies the problem of robust fault estimation (FE) observer design for discrete-
time Takagi–Sugeno (T–S) fuzzy systems via piecewise Lyapunov functions. Both the full …

In this paper, a discrete-time fuzzy disturbance observer (FDO) is developed and its
application to the control of a nonlinear system in the presence of the internal and external …
