DINCON'2010 - Brazilian Conference in Dynamics, Control and Their Applications

Professor Angelo Luongo mainly works on Dynamics and Stability of Elastic Structures, with particular interest to geometrically nonlinear systems. He is author of about one hundred fifty scientific papers, most of which (about sixty) published on International Journals. He is reviewer of several international journals on the field. His main research topics are:
* Linear free oscillations of elastic suspended cables;
* Nonlinear oscillations of one dimensional, elastic, structural systems (wires, beams);
* Critical and post-critical behavior of thin-walled beams;
* Nonlinear interaction among nearly-simultaneous buckling modes;
* Nonlinear dynamics of wires orbiting systems;
* Localization phenomena in Dynamics and Buckling;
* Sensitivity analysis of defective and nearly-defective dynamical systems;
* Aero-elastic stability phenomena in linear and nonlinear systems;
* Passive control of aero-elastic oscillations by Tuned Mass Dampers;
* Perturbation methods for multiple-bifurcations analysis of multi-parameter systems;
* Perturbation methods for discrete-time systems and piecewise systems;
* Dynamics and buckling of linear and nonlinear periodic systems.

This talk deals with computational aspects of two industrial problems, active vibration control and finite element model updating arising in mechanical vibration and structural dynamics. Active vibration control refers to controlling dangerous vibrations in mechanical structures, such as buildings, bridges, highways, automobiles, air and space crafts, and others. The most important part of this design is to compute two feedback matrices in real-time in a numerically effective way. For robust and economic control design, these feedback matrices must be found in such a way that they have the norms as small as possible and the condition number of the closed-loop control systems is minimized. These considerations give rise to two nonlinear unconstrained optimization problems, known respectively, as the Robust Quadratic Partial Eigenvalue Assignment Problem (RQPEVAP) and Minimum Norm Quadratic Partial Eigenvalue Assignment Problem (MNQPEVAP). The other one, Finite Element Model Updating Problem (FEMUP) arising in the design and analysis of structural dynamics, refers to updating an analytical finite element model so that a set of measured eigenvalues and eigenvectors from a real-life structure are reproduced and the physical and structural properties of the original model are preserved. A properly updated model can be used in confidence for future designs and constructions. Another major application of FEMUP is the damage detections in structures. Solutions of FEMUP also give rise to several constrained nonlinear constrained optimization problems.
I shall give an overview of the recent developments on computational methods for these difficult nonlinear optimization problems and discuss directions of future research. The talk is interdisciplinary in nature and will be of interests to mathematicians, computational and applied mathematicians, and control and vibration engineers

Title: State-constrained optimal control problems lacking controllabiltiy assumptions.

Abstract: We are interested in the characterization of the value function of a state-constrained control problem lacking controllability assumptions. In the unconstrained case, it is possible to derive the characterization of the value function by means of a Hamilton-Jacobi-Bellman (HJB) equation. This equation expresses the behavior of the value function along the trajectories arriving or starting from any position x. In the constrained case, when no controllability assumption is made, the HJB equation may have several solutions. Our first result aims to give the precise information that should be added to the HJB equation in order to obtain a characterization of the value function. This result is very general and holds even when the dynamics is not continuous and the state constraints set is not smooth. We shall also discuss some stability results for penalized control problems.

Title: Analysis and Control of Coupled Slow and Fast Systems
Summary: The presentation surveys a novel approach to the modeling, analysis and computations of coupled fast and slow dynamical systems; the latter include dynamics depicted by differential equations and control systems. The technique utilizes evolution of probability distributions each forms an invariant measure of the dynamics. Concrete examples will be displayed along with the theory.
