摘要: 采用最小二乘支持向量机的方法对GE公司PG9171E型燃气轮机的气耗特性进行了高精度拟合研究并与传统的最小二乘法的拟合结果进行了比较。仿真和试验结果表明,采用最小二乘支持向量机的方法在燃气轮机的变温度、变负荷等变工况下,气耗率的拟合可得到更加精确的结果。

Abstract: Using the LS-SVM method, the high accuracy fit study of the gasconsumption characteristics of PG9171E gas turbine manufactured by CE was carried out. The result was compared with that obtained by the traditional least square method. It is shown by the simulation and the experiment result that under the conditions of the gas turbine with varying temperature and varying load, the fitted result of the gas consumption obtained by LS-SVM method is more accurate.
