Abstract. The performance of a dynamic system of the “2D input – output” class with duplicate channels is shown to retain provided that argument of rotation matrix of cross-talk links does not exceed phase stability margin for a separate channel of the system. A method is proposed to increase the stability in scalar polynomial dynamic models.
Keywords: dynamic system, cross-talk links, rotation matrix, stability factor.
