Parametric identification of parallel Wiener–Hammerstein systems

Abstract: a b s t r a c tBlock-oriented nonlinear models are popular in nonlinear modeling because of their advantages to be quite simple to understand and easy to use. To increase the flexibility of single branch block-oriented models, such as Hammerstein, Wiener, and Wiener-Hammerstein models, parallel block-oriented models can be considered. This paper presents a method to identify parallel Wiener-Hammerstein systems starting from input-output data only. In the first step, the best linear approximation is estimated f… Show more

“…While the whiteness of the measurement errors are assumed, it can be removed, provided that the measurement errors have finite memory with memory length relatively small compared with the data length. This method can also be used in solving the parameter estimation problem of other nonlinear systems [19,20], such as Hammerstein and Wiener systems [21,22,23], block-oriented nonlinear systems [24,25,26].…”

“…It is also being applied in modelling and control design in control engineering field [11]. The advantages of using a block-oriented nonlinear model like H-W are it is simple to understand and easy to use [12]. Thus, it is suitable to apply H-W method to model the head tilt movement behaviour which is nonlinear in nature.…”
