Optimization design of RBF‐ARX model and application research on flatness control system

Abstract: The radial basis function (RBF) network and autoregressive exogenous (ARX) model are combined to form the structure of the RBF-ARX model. The RBF-ARX model can describe the global nonlinear dynamic process of the object, and its function coefficients are approximated by data-driven method. The structured nonlinear parameters optimization method (SNPOM) is generally used to optimize model parameters, but this method is very complicated and hard to be mastered by engineers. However, genetic algorithm (GA) is sim… Show more

“…When an iteration point is on the boundary of a constraint, if the feasible direction is not obtained properly, then only a small movement can be made along the direction due to the proximity of another constraint boundary. Otherwise, the iteration point will run out of bounds [26][27][28][29]. The Zoutendijk algorithm steps are as follows:…”

“…Not only can the analysis of actual flatness condition be conducted in real time but also the reasonable adjustment strategy is intelligently selected in the intelligent flatness control system [23][24][25]. As a consequence, the overall regulation capacity of flatness adjustment actuator after the combination is made to match with the flatness defect.…”

“…Simulation results under various methods show that the various models proposed can identify common defects in strip shape with high accuracy. Deng et al [25,26] constructed a hybrid model based on the combination of hot strip rolling production data and deep learning networks to predict strip outlet crown, achieving an absolute error of less than 5 µm for 97.04% of the predicted data in the modeling data. Song et al [27] used machine learning algorithms to establish an accurate prediction model for the strip crown of hot rolling.…”
