On an Active Control for a Structurally Nonlinear Mechanical System, Taking Into Account an Energy Pumping
(Asme-amer Soc Mechanical Eng, 2009-07-01)
The purpose of this work is to investigate the control of the oscillations and the suppression of vibrations in damped and coupled oscillators. In this sense, we look into the potential of using a nonlinear energy sink in ...
A nonlinear electromechanical pendulum arm with a Nonlinear Energy Sink control (NES) approach
(2016-01-01)
This paper considers the nonlinear dynamics of an electromechanical device with a pendulum arm and a Nonlinear Energy Sink (NES) put on the point of the pendulum suspension. It is shown that the (NES) is capable of absorbing ...
Nonlinear ball and beam control system identification
(2014)
The Ball and Beam system is a common didactical experiment in control laboratories that can be used to illustrate many different closed-loop control techniques. The plant itself is subjected to many nonlinear effects, which ...
Chaos control and sensitivity analysis of a double pendulum arm excited by an RLC circuit based nonlinear shaker
(2015)
In this paper the dynamical interactions of a double pendulum arm and an electromechanical shaker is investigated. The double pendulum is a three degree of freedom system coupled to an RLC circuit based nonlinear shaker ...
Estabilização de sistemas fuzzy T-S incertos usando realimenta̧ão derivativa
(2011-05-01)
In some practical problems, for instance, in the suppression of vibration in mechanical systems, the state-derivative signals are easier to obtain than the state signals. Thus, a method for state-derivative feedback design ...
EXPERIMENTAL OBSERVATION OF NONLINEAR VIBRATIONS USING A CLOSED-LOOP VIBRATION SYSTEM
(Polish Acad Sciences, 2015-12-01)
This paper presents experimental observation of nonlinear vibrations in the response of a flexible cantilever beam to transverse harmonic base excitations around its flexural mode frequencies. In the experimental setup, ...
On Switched Controller Design for Robust Control of Uncertain Polynomial Nonlinear Systems Using Sum of Squares
(2018-01-01)
This manuscript presents a switched control design for robust control of a class of uncertain nonlinear systems. In particular, it is considered a class of nonlinear systems whose dynamics are described by polynomial ...
Penalty-based nonlinear solver for optimal reactive power dispatch with discrete controls
(2013-04-15)
The optimal reactive dispatch problem is a nonlinear programming problem containing continuous and discrete control variables. Owing to the difficulty caused by discrete variables, this problem is usually solved assuming ...
