This document provides a brief proposal for “Robust Optimization & Robust Control Synthesis” reading group.

In [13], we introduced and analyzed a recovery-based a posteriori error estimator for conforming linear finite element approximation to interface problems. It was shown theoretically that the estimator is robust with respect to the size of jumps provided that the distribution of coefficients is locally monotone. Numerical examples showed that this condition is unnecessary. This paper extends th...

A numerical method is proposed for optimal robust control synthesis. The method applies to the case when the coefficients of the characteristic polynomial depend linearly on the uncertain parameters. A primal/dual pair of infinite-dimensional convex problems is solved by successive finite-dimensional approximations. The primal/dual pair has no duality gap, and both upper and lower bounds produc...

the robustness property can be added to dsc system at the expense of reducing performance, i.e., increasing the sum-rate. the aim of designing robust dsc schemes is to trade off between system robustness and compression efficiency. in this paper, after deriving an inner bound on the rate–distortion region for the quadratic gaussian mdc based rdsc system with two encoders, the structure of the r...

In this paper, we consider the problem of robust H finite-time control for a class of switched stochastic systems with time delay. Firstly, the concept of finite-time boundedness is extended to switched stochastic systems. Then, based on the average dwell time method, some sufficient conditions under which switched stochastic systems are finite-time stochastically bounded are given. Moreover, f...

Fluid-driven fracture propagation is widely observed in various geological processes and crucial to many applications of engineering. Developing robust accurate numerical strategies has significance advancing the scientific understanding engineering related with fluid-driven propagation. We present a finite element-finite volume strategy using asymptotic tip enrichment model three-dimensional C...

A numerical method for free-surface flow is presented at the aim of studying water waves in coastal areas. The method builds on the nonlinear shallow water equations and utilizes a non-hydrostatic pressure term to describe short waves. A vertical boundary-fitted grid is used with the water depth divided into a number of layers. A compact finite difference scheme is employed that takes into acco...
