Abstract
This chapter deals with the problem of \(\mathscr {H}_2\)-optimization of the standard model of a time-delayed SD system \(\mathscr {S}_\tau \) affected on its input by a colored stochastic stationary signal. To solve the problem, at the input of the \(\mathscr {S}_\tau \) system, a corresponding stable input shaping filter is added, and then the application of the optimization algorithm described in Chap. 7 is possible. This approach leads to a modified PTM, and unlike the approach currently used, is not related to the extension of the state space of a continuous object. The application of this method formally leads to the conclusion that the fixed poles of the \(\mathscr {H}_2\)-optimal system contain the external poles generated by the shaping filter for the input signal. A detailed examination of the solution obtained shows that these external poles can be shortened and the set of fixed poles for the problem of \(\mathscr {H}_2\)-optimization is the same in cases of white and colored input noise.
