Construction of robustly stable interval polynomial

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

The paper presents an original algorithm to determine the intervals of characteristic polynomial coefficients, which ensure its robust stability. This algorithm is built in conditions that provide linking indexes of stability and oscillation with interval coefficients of the characteristic polynomial. The paper reviews application of the algorithm for determination of the interval settings in a robust PID-controller. Performance of the algorithm was tested by construction of localization regions of the roots of the interval polynomial upon the determined intervals of the controller parameters.
