Modeling of Turbine-Boiler Coordinated System Based on Online Support Vector Machine

Abstract

Abstract. The simplified non-linear unit model not only can provide the inherent rules by control system design, but also can be use as a simulation process to evaluate the performance of the control algorithms. Using the nonlinear mapping characteristics of Online Support Vector Machine (Online SVM), the dynamic mathematical models of turbine-boiler coordinated system were established, and the simulation research were conducted. Operation data simulation shows that the model can perfectly reflect the dynamic characteristics of turbine-boiler coordinated system. When a new condition appeared in the process which did not include in the working condition data, the model can take advantage of the new data to realize online update, adding a new support vector, thus has a good reappearance.
