Improving the stability conditions of TS fuzzy systems with fuzzy Lyapunov functions
(2011-12-01)
In this paper, the fuzzy Lyapunov function approach is considered for stabilizing continuous-time Takagi-Sugeno fuzzy systems. Previous linear matrix inequality (LMI) stability conditions are relaxed by exploring further ...
Less conservative conditions for stabilization of switched TS fuzzy systems using fuzzy Lyapunov functions
(Ieee, 2018-01-01)
Relaxed conditions to stabilize switched TS fuzzy systems are proposed. The method considers the addition of slack matrix variables to decrease the conservatism of LMI-based stability conditions. The proposed method is an ...

Stability conditions of TS fuzzy systems with switched polynomial Lyapunov functions
(2020-01-01)
Exploring properties of membership functions, sufficient conditions based on linear matrix inequalities (LMIs) for a existence of a switched polynomial Lyapunov function are proposed. To obtain the LMIs, the time derivative ...
Switched Control and Tracking Application in Aeropendulum System using Fuzzy Models
(2021-07-11)
Switched robust controllers are presented and applied to an aeropendulum system made at the Control Research Laboratory from DEE-FEIS-UNESP in Brazil. The system has nonlinear dynamics and it is approximated by Takagi-Sugeno ...
On Robust Switched Controller Design to Minimize the Guaranteed Cost of Polynomial Fuzzy Systems
(2019-06-01)
This paper presents a robust switched controller design to minimize an upper bound of a quadratic index (guaranteed cost) based on the output and the control input of uncertain nonlinear systems described by polynomial ...
On switched control of discrete-time Takagi-Sugeno fuzzy systems with unknown membership functions
(Ieee, 2018-01-01)
A switched control design for a class of uncertain nonlinear discrete-time systems is proposed in this manuscript. The proposed procedure uses Takagi-Sugeno fuzzy models to describe the nonlinear systems and the membership ...
