A nonlinear interval number programming method for uncertain optimization problems

In this paper, a method is suggested to solve the nonlinear interval number programming problem with uncertain coefficients both in nonlinear objective function and nonlinear constraints. Based on an order relation of interval number, the uncertain objective function is transformed into two deterministic objective functions, in which the robustness of design is considered. Through a modified po...

Interval uncertain optimization of structures using Chebyshev meta-models

This paper proposes a new design optimization method for structures subject to uncertainty. Interval model is used to account for uncertainties of uncertain-but-bounded parameters. It only requires the determination of lower and upper bounds of an uncertain parameter, without necessarily knowing its precise probability distribution. The interval uncertain optimization problem will be formulated...

Robust control of uncertain structures

Objective of this paper is to present robust control strategies able to handle acceleration feedback. The robustness of the controller is investigated in respect to both stability and performance measures. The uncertainty set is chosen as a convex one with either real or complex structured uncertainty. H1 control is ®rstly used to comply with the stability requirements whereas a m synthesis app...

Buckling Analysis of Structures with Uncertain Properties and Loads Using an Interval Finite Element Method

In order to ensure the safety of a structure, one must provide for adequate strength of structural elements. In addition, one must prevent large unstable deformations such as buckling. In most analyses of buckling, structural properties and applied loads are considered certain. This approach ignores the fact that imperfections and unknown changes in properties, albeit small, are required for on...

Robust dissipativity of interval uncertain systems

In this paper we are concerned with the problem of robust dissipativity of linear systems with parameters affected by box uncertainty; our major goal is to evaluate the largest uncertainty level for which all perturbed instances share a common dissipativity certificate. While it is NP-hard to compute this quantity exactly, we demonstrate that under favourable circumstances one can build an O(1)...
