O projektu

Projekt se věnuje problematice popisu, analýze a návrhu analogových fraktálních obvodů. Jsou řešeny problémy matematického popisu aproximující chování vybraných obvodových struktur, návrhu fraktálních prvků vhodných praktickou implementaci a návrhu a analýze funkčních řešení lineárních bloků určených pro praktickou realizaci PID kontrolérů a jiných analogových komplexních celků.

Popis anglicky
Project focuses on areas of description, analysis and synthesis of analog circuits of fractional order, i.e. non-integer order. Problems of mathematical description of behaviour of particular circuit structures are solved. Project is also focused on analysis of functional solutions of linear blocks of fractional order (e.g. frequency filters, oscillators, integrators, derivators, immitance elements) dedicated for practical realization of analogue complex units. Synthesis and analysis of fractional circuit elements suitable for practical implementation of above noted linear blocks is also goal of the project.
