- Abstract
For the lack of theoretical basis for the model selection during establishing the piecewise linear model of gas turbine, the concept of the gap metric was introduced to indicate the similarity between the linear models and to achieve the non-redundant selection of the piecewise linear model. The method was applied to establish the piecewise linear model for a two-shaft gas turbine, and then compared with the piecewise linear model established by equal interval model selection method. The results showed that the proposed method not only can provide a theoretical basis for the model selection of the piecewise linear model, but also ensures high precision while greatly reducing the number of linear models and avoiding model redundancy.
