Stability of nonlinear system using takagi-sugeno fuzzy models and hyper-rectangle of LMIs
(2013-04-01)
This paper presents a theorem based on the hyper-rectangle defined by the closed set of the time derivatives of the membership functions of Takagi-Sugeno fuzzy systems. This result is also based on Linear Matrix Inequalities ...
Design of a fuzzy Takagi-Sugeno controller to vary the joint knee angle of paraplegic patients
(Springer, 2006-01-01)
The papers shows, through theoretical studies and simulations, that using the description of the plant by Takagi-Sugeno (T-S), it is possible to design a nonlinear controller to control the position of the leg of a paraplegic ...
Controle ótimo H∞ de sistemas não-lineares com modelos fuzzy takagi-sugeno
(Sociedade Brasileira de Automática, 2008-09-01)
Neste trabalho é proposta uma metodologia de rastreamento de sinais e rejeição de distúrbios aplicada a sistemas não-lineares. Para o projeto do sistema de rastreamento, projeta-se os controladores fuzzy M(a) e N(a) que ...
Realimentação derivativa e modelo fuzzy Takagi-Sugeno paracontrole da articulação do joelho de pacientes paraplégicos com o uso de acelerômetros
(2011-06-01)
Feedback control systems have been used to move the muscles and joints of the limbs of paraplegic patients. The feedback signal, related to the knee joint angle, can be obtained by using an electrogoniometer. However, the ...
On relaxed LMI-based designs for fuzzy regulators and fuzzy observers
(Institute of Electrical and Electronics Engineers (IEEE), 2003-10-01)
Relaxed conditions for stability of nonlinear, continuous and discrete-time systems given by fuzzy models are presented. A theoretical analysis shows that the proposed methods provide better or at least the same results ...
Estabilização de sistemas fuzzy T-S incertos usando realimenta̧ão derivativa
(2011-05-01)
In some practical problems, for instance, in the suppression of vibration in mechanical systems, the state-derivative signals are easier to obtain than the state signals. Thus, a method for state-derivative feedback design ...
On Switched Regulator Design of Uncertain Nonlinear Systems Using Takagi-Sugeno Fuzzy Models
(Ieee-inst Electrical Electronics Engineers Inc, 2015)
Design of a Takagi-Sugeno Fuzzy Regulator for a Set of Operation Points
(Hindawi Publishing Corporation, 2012-01-01)
The paper proposes a new design method based on linear matrix inequalities (LMIs) for tracking constant signals (regulation) considering nonlinear plants described by the Takagi-Sugeno fuzzy models. The procedure consists ...
