Synthesis of Variable Gain Robust State Observer for Linear Systems With Structured Uncertainties
IEEE AccessThis paper proposes a new variable gain robust state observer for a class of linear uncertain systems. The variable gain robust state observer proposed in this paper consists of fixed observer gain matrices and nonlinear modification functions which are ...

On an Optimal -Control Problem in Coefficients for Linear Elliptic Variational Inequality
Abstract and Applied Analysis, 2013 We consider optimal control problems for linear degenerate elliptic variational inequalities with homogeneous Dirichlet boundary conditions. We take the matrix-valued coefficients in the main part of the elliptic operator as controls in .
