Saratov State Technical University, Department of Technical Cybernetics and Informatics;; Post-Graduate Student
Abstract. Program realization of the problem of tolerances estimation of tolerances on elements of automated control system is considered. The problem reduces to calculation of upper and low limits for coefficients of interval polynomial attendant with a given Hurwitz characteristic polynomial describing a closed-loop control system with a regulator. Solution to the problem is obtained with the use of Hermite – Biller polynomials and Vieta formulas in an alternative form.
