Combined Enhanced LMI Charactrization and Parametric Eigenstructure Assignment Using Static Output Feedback [PDF]

Journal of Intelligent Procedures in Electrical Technology, 2012
This paper proposes mixed eigenstructure assignment with H∞ constraint when the states are not measurable. In this case, full state feedback is not permissible. So eigenstructure assignment by output feedback is considered.

The matricial relaxation of a linear matrix inequality

, 2011
Given linear matrix inequalities (LMIs) L_1 and L_2, it is natural to ask: (Q1) when does one dominate the other, that is, does L_1(X) PsD imply L_2(X) PsD? (Q2) when do they have the same solution set? Such questions can be NP-hard. This paper describes

Aeroelastic stability analysis using linear matrix inequalities [PDF]

Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2012
The present work describes an alternative methodology for identification of aeroelastic stability in a range of varying parameters. Analysis is performed in time domain based on Lyapunov stability and solved by convex optimization algorithms. The theory is outlined and simulations are carried out on a benchmark system to illustrate the method.

Robust Distributed H∞ Filtering for Nonlinear Systems with Sensor Saturations and Fractional Uncertainties with Digital Simulation

Discrete Dynamics in Nature and Society, 2015
This paper is concerned with the robust distributed H∞ filtering problem for nonlinear systems subject to sensor saturations and fractional parameter uncertainties. A sufficient condition is derived for the filtering error system to reach the required H∞

Determinant Maximization with Linear Matrix Inequality Constraints [PDF]

SIAM Journal on Matrix Analysis and Applications, 1998
Summary: The problem of maximizing the determinant of a matrix subject to linear matrix inequalities (LMIs) arises in many fields, including computational geometry, statistics, system identification, experiment design, and information and communication theory. It can also be considered as a generalization of the semidefinite programming problem.

Robust and Resilient Finite-Time Control of a Class of Discrete-Time Nonlinear Systems [PDF]

, 2011
In this paper, we address the finite-time state-feedback stabilization of a class of discrete-time nonlinear systems with conic type nonlinearities, bounded feedback control gain perturbations, and additive disturbances.
