Accurate Model Identification for Non-Invertible MIMO Sandwich Block-Oriented Processes

In the previous work our research group introduced an exact solution to the Hammerstein system and is known as H-BEST (Hammerstein BlockOriented Exact Solution Technique). It was later expanded to multiple input, multiple output (MIMO) Hammerstein and Wiener (W-BEST) systems. This work is extends this approach to more complicated block-oriented systems, namely a Hammerstein-Wiener process. By exploiting a closed form solution, the proposed method has the major advantages of being simple to build and implement the model, and does not require a complex algorithm or solution to a difficult optimization problem. The method is evaluated and compared to another method. With a slower sampling rate, the proposed method is shown to provide a higher level of predictive accuracy.
