A nonlinear and non-ideal wind generator supporting structure
(2006-10-09)
We present a simple mathematical model of a wind turbine supporting tower. Here, the wind excitation is considered to be a non-ideal power source. In such a consideration, there is interaction between the energy supply and ...
Digital control system for two-beam optical interferometry using variable structure and sliding modes method
(2019-01-01)
Laser interferometry is recognized as an extremely sensitive measurement technique, capable of detecting quantities that conventional sensors usually cannot. However, such advantage also brings a challenge, the interferometer ...
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 ...

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 ...
Nonlinear dynamic modeling, identification and control of a slewing flexible structure
(2003-12-01)
This work deals with nonlinear dynamic modeling of a flexible slewing structure. The interaction between the slewing motion and the structure deflection has been modeled taking in account the nonlinear curvature of the ...
Nonlinear angle control of a sectioned airfoil by using shape memory alloys
(E D P Sciences, 2014-01-01)
The present work illustrates an application of shape memory alloys and nonlinear controller applied to the active angular control of a sectioned airfoil. The main objective of the proposed control system is to modify the ...
Degenerate hope bifurcations in Chua's system
(2009-02-01)
In this paper we study the local codimension one, two and three Hopf bifurcations which occur in the classical Chua's differential equations with cubic nonlinearity. A detailed analytical description of the regions in the ...
Swarm control designs applied to a micro-electro-mechanical gyroscope system (MEMS)
(2010-12-01)
This paper analyzes the non-linear dynamics of a MEMS Gyroscope system, modeled with a proof mass constrained to move in a plane with two resonant modes, which are nominally orthogonal. The two modes are ideally coupled ...
SDRE control strategy applied to a nonlinear robotic including drive motor
(Amer Inst Physics, 2014-01-01)
A robotic control design considering all the inherent nonlinearities of the robot-engine configuration is developed. The interactions between the robot and joint motor drive mechanism are considered. The proposed control ...
