Abstract. A synthesis procedure is proposed to diminish stabilization system sensitivity to parametric uncertainty of object under control. The procedure is based on artificial separation of the object movements and extension of dynamic model. The proposed method is represented in the frames of Н2-optimal control and linear quadratic Gaussian problem.
