# Parametric Synthesis of a Robust Controller on a Base of Interval Characteristic Polynomial Coefficients

### Sergey Gayvoronskiy, Tatiana Ezangina, Ivan Khozhaev

#### Abstract

The paper is dedicated to deriving sufficient conditions, connecting root quality indexes of the control system with interval coefficients of its characteristic polynomial, on the base of interval expansion of the coefficient method. With the help of these conditions, a method of synthesizing a controller, providing an aperiodic transient process and acceptable stability degree, was developed. The method is applied to a problem of synthesizing a controller of an autonomous underwater vehicle submerging control system with interval parameters.
