New algorithm for spectral factorization and its application in signal processing
Ježek, Jan ; Hromčík, Martin ; Šebek, Michael
In this report a new algorithm is presented for the spectral factorization of a two-sided symmetric polynomial. The method is based on the discrete Fourier transform theory (DFT) and its relationship to the Z-transform. Involving DFT computational techniques, namely the famous fast Fourier transform routine (FFT), brings high computational efficiency and reliability. The power of the proposed procedure is employed in a particular practical signal processing application.
Simultaneous feedback stabilization: A survey
Hurák, Zdeněk ; Šebek, Michael
This paper gives a short introduction into the topic of simultaneous feedback stabilization, which is recognized as one of the fundamental open problems in control theory. In this paper, some essential defnitions are given, the relation between strong and simultaneous stability is explained, the recent result on complexity of the topic is stated, and some recent approaches based on LMI paradigm are described. SISO systems are considered only.
MATLAB function for polynomial plus/minus factorization based on band structured matrix decomposition
Hromčík, Martin ; Šebek, Michael
A new algorithm for the plus/minus factorization of a scalar discrete-time polynomial and its implementation in the MATLAB programming language are presented in this report. The objects and standard routines of the "Polynomial Toolbox for MATLAB" are employed. The methods is based on the relationship of polynomial algebra to the algebra of band structured ininite dimensional matrices.
