HARMONIC STATIONARIZATION METHOD AND EVALUATION OF ROBUSTNESS OF PERIODIC TIME-VARIANT CONTROL SYSTEMS

Leonid Chechurin, St. Petersburg State Polytechnical University, St. Petersburg, Cand.Sc., Head of Dept. (cepreu4@gmail.com).

Abstract: An approach to evaluation of stability of linear periodic time-variant control system over various description uncertainties is given. The stability bounds are derived with the help of harmonic stationarization method, that obtains transfer functions for periodic time-variant elements within one-frequency approximation.

Keywords: frequency analysis, harmonic stationarization, robustness of time-variant systems.
