ABSTRACT

The identification problem of linear stationary dynamic systems in the state space with frequency characteristics is considered. An improved method of constructing approximate models under bounded uncertainty is proposed. The parameters determination problem is reduced to minimization of a nonlinear functional, allowing one to use stochastic methods for finding solutions.
