On the project

Projekt je zaměřen na řešení problému identifikace nelineárních dynamických systémů s využitím modelů se zlomkovými derivacemi. S tím souvisí výzkum metod analýzy systémů se zlomkovým řádem - zlomkových systémů (úlohy o stabilitě zlomkových systémů se zpožděním, úlohy řiditelnosti a pozorovatelnosti pro zlomkové systémy se zpožděním a jejich numerická řešení) a následný vývoj originálních metod pro adaptivní odhad zlomkových systémů pomocí Bayesovského přístupu a identifikace zlomkových systémů Laguerrovou identifikací. Výstupem projektu budou nové přístupy k identifikaci dynamických systémů založených na zlomkových modelech. Důraz bude kladen na analýzu a identifikaci nelineárních a časově proměnných systémů.

Description in English
The project focuses on solving the problem of identification of nonlinear fractional dynamical systems using models with fractional derivatives. With this is related investigation of methods of analysis of systems with fractional order – fractional systems (fractional delay stability problems, control and observability problems for fractional delayed systems and their numerical solution) and subsequent research of original methods for adaptive estimation of fractional systems from the Bayesian perspective and Laguerre based identification of fractional order systems. As outputs the project will provide new approaches to the identification of dynamical systems based on fractional models. An emphasis will be placed on the analysis and identification of nonlinear and time varying systems.
