Discrete–Time Linear Systems with Desired Poles and Zeros of the Transfer Matrices

open access: yesInternational Journal of Applied Mathematics and Computer Science
Methods for the design of discrete-time linear systems with desired poles and zeros of their transfer matrices are proposed. Conditions for the existence of the solution to the problem and the procedures for computation of the desired matrices are given.

Nilpotent Approximation and Nilpotentization for Under-Actuated Systems on Matrix Lie Groups [PDF]

open access: yes, 2007
This paper develops a method for constructing nilpotent approximations for local representations of invariant systems on matrix Lie groups via a simple operation on the structure constants of the associated Lie algebra.

First order linear ordinary differential equations in associative algebras

open access: yesElectronic Journal of Differential Equations, 2004
In this paper, we study the linear differential equation $$ frac{dx}{dt}=sum_{i=1}^n a_i(t) x b_i(t) + f(t) $$ in an associative but non-commutative algebra $mathcal{A}$, where the $b_i(t)$ form a set of commuting $mathcal{A}$-valued functions expressed ...
