Active control in rotating machinery using magnetic actuators with linear matrix inequalities (LMI) approach
(2009-12-01)
The recent years have seen the appearance of innovative system for acoustic and vibration attenuation, most of them integrating new actuator technologies. In this sense, the study of algorithms for active vibrations control ...
On a control design to an AFM microcantilever beam, operating in a tapping-mode, with irregular behavior
(2011-12-01)
In last decades, control of nonlinear dynamic systems became an important and interesting problem studied by many authors, what results the appearance of lots of works about this subject in the scientific literature. In ...
On an optimal control applied in atomic force microscopy (AFM) including fractional-order
(2017-01-01)
In this work, the nonlinear dynamics of an Atomic Force Microscope (AFM) operating in tapping mode is investigated, considering the influence of squeeze film damping in fractional-order. Its influence plays an important ...

SDRE CONTROL APPLIED TO AN ELECTROMECHANICAL PENDULUM EXCITED BY A NON-IDEAL MOTOR
(Amer Soc Mechanical Engineers, 2014-01-01)
The dynamical behavior of an electromechanical pendulum system is analyzed by means of the classical perturbation theory. A frequency response model of the system is obtained, and the number of unstable poles are determined ...
Sdre control applied to an electromechanical pendulum excited by a non-ideal motor
(2013-01-01)
The dynamical behavior of an electromechanical pendulum system is analyzed by means of the classical perturbation theory. A frequency response model of the system is obtained, and the number of unstable poles are determined ...
Chandler wobble: Stochastic and deterministic dynamics
(2016-09-18)
We propose a model of the Earth’s torqueless precession, the “Chandler wobble,” as a self-oscillation driven by positive feedback between the wobble and the centrifugal deformation of the portion of the Earth’s mass contained ...
