Abstract [en]

The problem of identification of Wiener systems with special types of hard and discontinuous nonlinearities in the presence of process and measurements noises in observations to be processed has been considered. It is shown, that the original problem could be reduced to the problem of determination of the subsystem from the auxiliary network of subsystems, equivalent to the true linear system (linear part of the Wiener system). A technique based on the ordinary least squares, to be used in a case of missing data, and on the expectation maximization algorithm is proposed here. The results of numerical simulation of the discrete-time Wiener systems with various hard and discontinuous nonlinearities by computer are given.
