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 ...
Behavioural Analysis of a Nonlinear Mechanical System Using Transient Trajectories
(2003-12-08)
This work aims at a better comprehension of the features of the solution surface of a dynamical system presenting a numerical procedure based on transient trajectories. For a given set of initial conditions an analysis is ...
The fractional-nonlinear robotic manipulator: Modeling and dynamic simulations
(2012-12-01)
In this paper, we applied the Riemann-Liouville approach and the fractional Euler-Lagrange equations in order to obtain the fractional-order nonlinear dynamics equations of a two link robotic manipulator. The aformentioned ...
A regularized nonlinear diffusion approach for texture image denoising
(2009-12-01)
In this paper a new partial differential equation based method is presented with a view to denoising images having textures. The proposed model combines a nonlinear anisotropic diffusion filter with recent harmonic analysis ...
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 ...
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 new sufficient condition for optimal impulsive control problems
(2012-12-01)
In this article we introduce the concept of MP-pseudoinvexity for general nonlinear impulsive optimal control problems whose dynamics are specified by measure driven control equations. This is a general paradigm in that, ...
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 ...
State Dependent Riccati Equation (SDRE) control method applied in cancellation of a parametric resonance in a magnetically levitated body
(2011-12-01)
Here, a simplified dynamical model of a magnetically levitated body is considered. The origin of an inertial Cartesian reference frame is set at the pivot point of the pendulum on the levitated body in its static equilibrium ...
