In this paper finite-dimensional singular linear discrete-time-invariant systems in the form Ex(k + 1) = Ax(k) + Bu(k), y(k) = Cx(k) where E;A 2 M = Mn(C), B 2 Mn£m(C), C 2 Mp£n(C), describing convolutional codes are ...
• #### Solving disturbance decoupling for singular systems by p&d-feedback and p&d-output injection ﻿

(IPACS Electrinic Library, 2011)
Capítol de llibre

Let P(¸) = Pk i=0 ¸iAi(p) be a family of monic polyomial matrices smoothly dependent on a vector of real parameters p = (p1; : : : ; pn). In this work we study behavior of a multiple eigenvalue of the monic polynomial family P(¸).
