Parametric and non-parametric probabilistic approaches in the mechanics of thin-walled composite curved beams
In this paper we perform a quantification of the uncertainty propagation of the dynamics of slender initially curved structures constructed with fiber reinforced composite materials. Depending on the manufacturing process, ...
Quantification of parametric uncertainties induced by irregular soil loading in orchard tower sprayer nonlinear dynamics
This paper deals with the nonlinear stochastic dynamics of an orchard tower sprayer subjected to random excitations due to soil irregularities. A consistent stochastic model of uncertainties is constructed to describe ...
Dynamics of thin walled composite beams: Analysis of parametric uncertainties
This article is concerned with the stochastic dynamic analysis of structures constructed with composite materials. Depending on many aspects (manufacturing process, material uncertainty, boundary conditions, etc.) real ...
The dynamic behavior of a parametrically excited time-periodic MEMS taking into account parametric errors
Micro-electromechanical systems (MEMS) are micro scale devices that are able to convert electrical energy into mechanical energy or vice versa. In this paper, the mathematical model of an electronic circuit of a resonant ...
An improved LMI condition for robust D-stability of uncertain polytopic systems

Estabilização de sistemas fuzzy T-S incertos usando realimenta̧ão derivativa
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 ...
Nonlinear control system applied to atomic force microscope including parametric errors
The performance of the optimal linear feedback control and of the state-dependent Riccati equation control techniques applied to control and to suppress the chaotic motion in the atomic force microscope are analyzed. In ...
