Damage detection in nonlinear structures using discrete-time volterra series
(2013-09-16)
Structural damage identification is basically a nonlinear phenomenon; however, nonlinear procedures are not used currently in practical applications due to the complexity and difficulty for implementation of such techniques. ...
Nonlinear Dynamic Behavior, Deterministic Chaos and Nonlinear Control of a Micro Electro Mechanical Actuator System (MEMS)
(Destech Publications, Inc, 2015-01-01)
Micro Electro Mechanical Systems (MEMS) are systems composite by electrical and mechanical devices that interact by means of transducers elements, thus constituting one single and whole system. On the study of dynamic ...
An extension of the invariance principle for switched T-S fuzzy systems
(IEEEEuropean Control Association (EUCA)Zurich, 2013)
In this work, we propose an extension of the
invariance principle for switched T-S fuzzy systems using
an auxiliary function V for the convex combination of the
subsystems which applies to unstable subsystems. The ...
Optimal linear and nonlinear control design for chaotic systems
(2005-12-01)
In this work, the linear and nonlinear feedback control techniques for chaotic systems were been considered. The optimal nonlinear control design problem has been resolved by using Dynamic Programming that reduced this ...
On Nonlinear Dynamics and Control Design in a MEMS Gyroscope System
(Springer, 2013-01-01)
This paper deals with a (MEMS) Gyroscope nonlinear dynamical system, modeled with a proof mass constrained to move in a plane with two resonant modes, which are nominally orthogonal. We present some modifications to the ...
A comparative study between two relaxed LMI-based fuzzy control designs
(2005-09-01)
A comparative study, with theoretical analysis and digital simulations, of two conditions based on LMI for the quadratic stability of nonlinear continuous-time dynamic systems, described by Takagi-Sugeno fuzzy models, are ...
On the response at the excitation frequency of a two degrees of freedom nonlinear oscillator
(2017-01-01)
This paper presents an overview of the main theoretical advances and experimental analyses, achieved by the authors in recent years of collaborative research in the field of nonlinear dynamics of coupled oscillators. The ...
Nonlinear Control Strategy based on Discrete-Time State Dependent Riccati Equation for Electronic Throttle Control
(Ieee, 2016-01-01)
This paper aims to present a new control strategy for eletronic throttle control (ETC) used for the acceleration function in a vehicle. Firstly, an analitical model describing is developed with the purpose to evaluation ...
Optimal linear control driven for piezoelectric non-linear energy harvesting on non-ideal excitation sourced
(2014-01-01)
Non-linear energy harvesting system was project to enhance interaction to ambient vibration that is wide band and low power which difficult the design for resonant solution. To improve efficiency of a non-linear design it ...
Characterization of grazing bifurcation in airfoils with control surface freeplay nonlinearity
(2014-01-01)
A variety of nonlinear features is obtained from aeroelastic systems with discontinuous nonlinearity motivates investigations that may support future applications in controls design, flutter prediction problems, and energy ...
