This manuscript proposes a robust switched controller design with minimization of an upper bound of a quadratic performance index (guaranteed cost) related to the system output for a class of uncertain nonlinear systems ...

This paper proposes conditions that ensure local ultimate bounded stability for nonlinear systems constrained to a region of operation, subject to actuator saturation and persistent norm-bounded disturbance. The nonlinear ...

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 ...

Este trabalho dedica-se ao estudo do problema de controle robusto envolvendo custo H∞ para sistemas lineares chaveados no tempo contínuo, sujeitos à saturação no atuador e com incertezas politópicas, considerando leis de ...

This paper considers a class of uncertain nonlinear systems exactly described by Takagi–Sugeno (T-S) fuzzy models, with or without matched uncertainties and/or disturbances, within an operating region in the state space. ...

This manuscript proposes a local H∞ switched controller design for a class of uncertain nonlinear plants described by Takagi–Sugeno (T–S) fuzzy models with unknown membership functions. The control design requires only the ...

A nanocomposite is fabricated by formation of a conductive polymer, using in situ oxidative polymerization, inside a thermosensitive crosslinked hydrogel. FE-SEM micrographs show the nanometric domains of the conductive ...
