Abstract :
In this paper new algorithm for robust stability analysis of linear systems with parametric uncertainty is presented. The algorithm is based on multivariate interpolation-evaluation methods and fast Fourier transform used for computing determinant of a multivariate polynomial matrix. Positivity of a multivariate polynomial on a hyperrectangle is tested by Bernstein algorithm. The high efficiency of the proposed algorithm is demonstrated on automatic steering control of Daimler Benz city bus - an 8th order closed-loop system with two uncertain parameters
