Variation diminution and intervals of sign regular matrices
Results in Applied MathematicsA sign regular matrix is a matrix having the property that its non-zero minors of all orders have, for each order, an identical sign. Such matrices arise in a wide range of applications. In this paper, intervals of real matrices with respect to the usual

A Mixed H2/H∞ Control Method for UAV Based on T-S Fuzzy Model
Kongzhi Yu Xinxi Jishu, 2018 A mixed H2/H∞ control strategy was proposed in this paper to achieve a stable tracking trajectory of the UAV(unmanned aerial vehicle). Firstly, the quadrotor UAV was divided into three subsystems: the altitude, the position and the attitude. By selecting

Interval matrix differential equations
, 2012 The matrix differential equation $x'(t) = Q(t)x(t), x(0) = x_0$ is considered in the case where $Q(t)$ is an unspecified matrix function of time, with the only constraint that $Q(t)\in \mset$ for every $t$, where $\mset$ is a prescribed closed and convex set of matrices.

Two Iterative Methods for Solving Linear Interval Systems
Applied Computational Intelligence and Soft Computing, 2018 Conjugate gradient is an iterative method that solves a linear system Ax=b, where A is a positive definite matrix. We present this new iterative method for solving linear interval systems Ãx̃=b̃, where à is a diagonally dominant interval matrix, as ...

Matrix Completion Under Interval Uncertainty: Highlights [PDF]
, 2019 We present an overview of inequality-constrained matrix completion, with a particular focus on alternating least-squares (ALS) methods. The simple and seemingly obvious addition of inequality constraints to matrix completion seems to improve the statistical performance of matrix completion in a number of applications, such as collaborative filtering ...
