Stochastyczna linearyzacja złożonych układów dynamicznych

The applications of stochastic linearization to multi-degree-of-freedom systems is considered in this paper. The systems have an interconnected structure i.e. they consist of many interconnected subsystems. The method of two step linearization is proposed. In the first step the subsystems will be linearized, in the second step the interconnections will be linearized. The comparison of computation time and accuracy of the proposed method with standard stochastic linearization is illustrated for a mechanical system with two degrees of freedom.
