However, by exploiting structure in the nonlinearity (. Hammerstein–Wiener, LPV) dedicated algorithms can be developed?[1,2,3].

Nonlinear System Modelling and Analysis from the Volterra and Wiener Perspective desired because it can be used to obtain new insights concerning a phenomenon and also to predict the outcome of experiments involving the phenomenon [5]. System theory, which is the theory of models, is thus fundamental to science. An important problem in system theory is the development of nonlinear models of phenomena.

Compound Operator Decomposition and Its Application to Hammerstein and Wiener Systemsility of control system descriptions we are usually forced to make proper assumptions and to use approximations and/or simplifications, hoping that any possible side effects will not be too severe. Therefore, the approaches dealing with nonlinear dynamic systems are generally restrictive in assumptions and applicable to special cases only.

Recursive Identification for Stochastic Hammerstein Systems setting, the linear part of the system is characterised by a rational transfer function (RTF) and the system output .. is exactly observed. However, in practice the system itself may be random and the observations may be corrupted by noises. So, it is of practical importance to consider stochastic Hammerstein systems as shown in Figure 6.1.

The concept of block-oriented models assumes that the real plant, as a whole, can be treated as a system of interconnected blocks, static nonlinearities (N) and linear dynamics (L), where the interaction signals cannot be measured.
