Linear- and Linear-Matrix-Inequality-Constrained State Estimation for Nonlinear Systems

IEEE Transactions on Aerospace and Electronic Systems, 2019
This paper considers nonlinear state estimation subject to inequality constraints in the form of linear and linear-matrix inequalities. Rewriting the standard maximum likelihood objective function used to derive the Kalman filter allows the Kalman gain ...

Linear Equations and Linear Inequalities

2002
While Chapter 1 reviews general structural aspects of real vector spaces, we now discuss fundamental computational techniques for linear systems in this chapter. For convenience of the discussion, we generally assume that the coefficients of the linear systems are real numbers.

Global Maximization of a Convex Function with Linear Inequality Constraints

Operational Research, 1974
This paper presents an algorithm for the global maximization of a convex function subject to linear inequality constraints. It is computationally finite and is designed to converge rapidly on problems in which there are few local optima or the global ...

Linear Matrix Inequality-Based Nonlinear Adaptive Robust Control of Quadrotor

, 2016
In this paper, we propose a novel linear matrix inequality-based nonlinear adaptive robust control algorithm to design the attitude and position controllers for an X-configuration quadrotor helicopter.

Linear Inequalities and Polyhedra

2014
The focus of this chapter is on the study of systems of linear inequalities Ax ≤ b. We look at this subject from two different angles. The first, more algebraic, addresses the issue of solvability of Ax ≤ b.

Linear matrix inequalities

IEE Proceedings - Control Theory and Applications, 2003
Linear matrix inequalities (LMIs) have emerged as a powerful tool for numerically solving control problems that are difficult or impossible to solve analytically. The idea is to express a given problem as an optimisation problem with linear objective and semidefinite constraints, where the constraints involve symmetric matrices that are affine in the ...

Solution of Linear Inequalities

IEEE Transactions on Computers, 1970
A method for solving systems of linear inequalities, consistent and inconsistent, corresponding to the separable and nonseparable cases in pattern recognition is presented. Attempts are made to evaluate the speed and efficiency of the algorithm.

Bayesian Analysis of the Linear Model Subject to Linear Inequality Constraints

, 1978
This article considers the general linear model when the parameter space is subject to linear inequality constraints. A Bayesian analysis of this model is presented using a natural conjugate prior of the mixed type.

Stability Theory for Linear Inequality Systems

SIAM Journal on Matrix Analysis and Applications, 1996
This paper develops a stability theory for (possibly infinite) linear inequality systems defined on a finite-dimensional space, analyzing certain continuity properties of the solution set mapping.
