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 ...
Realimentação da derivada dos estados em sistemas multivariáveis lineares usando LMIs
(Sociedade Brasileira de Automática, 2009-03-01)
Em alguns problemas práticos, por exemplo em sistemas mecânicos para controle de vibrações, é mais fácil obter o sinal da derivada dos estados do que os sinais dos estados. Uma nova técnica para estabilização de sistemas ...
New Design of Robust LQR-State Derivative Controllers via LMIs
(2018-01-01)
The resolution of linear quadratic regulator's problem (LQR) approached via linear matrix inequalities (LMIs) for linear and time-invariant systems is proposed in this work. The design of the controllers is based on 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 ...
Parameter-dependent Lyapunov functions for state-derivative feedback control in polytopic linear systems
(Taylor & Francis Ltd, 2011-01-01)
In some practical problems, for instance, the suppression of vibration in mechanical systems, the state-derivative signals are easier to obtain than the state signals. Using Linear Matrix Inequalities (LMIs), and applying ...
Design of an gain scheduling state derivative feedback controller for linear parameter-varying systems
(2021-01-01)
This paper is devoted to the guaranteed cost (Formula presented.) of continuous-time linear parameter-varying (LPV) systems, considering the gain scheduling (GS) strategy and the state derivative feedback (SDF). The main ...
On Switched Regulator Design of Uncertain Nonlinear Systems Using Takagi-Sugeno Fuzzy Models
(Ieee-inst Electrical Electronics Engineers Inc, 2014-12-01)
This paper is concerned with the design of state-feedback switched controllers for a class of uncertain nonlinear plants described by Takagi-Sugeno (T-S) fuzzy models. The proposed methodology eliminates the need to find ...
On switched control design of linear time-invariant systems with polytopic uncertainties
(2013-05-27)
This paper proposes a new switched control design method for some classes of linear time-invariant systems with polytopic uncertainties. This method uses a quadratic Lyapunov function to design the feedback controller gains ...
