This research focuses on the recursive identification for electric arc furnace — electrode regulator system. Based on the comprehensive study of the aforementioned system structure, we express the electrode regulator system by a Hammerstein-Wiener nonlinear block-oriented model and give its parameterized form. Furthermore, an algorithm is proposed for the recursive identification of the model. The...
Identifying an accurate model of the stagnation pressure on-line will benefit the design of the controller and improve the quality of the wind tunnel experiments. This paper focuses on the recursive identification of the stagnation pressure in the wind tunnel system. Based on the study of the aforementioned system structure, the stagnation pressure system is expressed by a block oriented model with...
A recursive algorithm is proposed in this paper to identify Hammerstein–Wiener systems with heteroscedastic measurement noise. Based on the parameterization model of Hammerstein–Wiener systems, the algorithm is derived by minimizing the expectation of the sum of squared parameter estimation errors. By replacing the immeasurable internal variables with their estimations, the need for the commonly used...
