摘要：

This paper describes the estimation of parametric and nonparametric models of the fuel feed to shaft speed dynamics of a twin-shaft gas turbine engine, using frequency-domain techniques. Data gathered from practical testing of the turbine are presented and shown to be of high quality. Accurate models are then estimated at several points along the turbine operating curve. The results of the parametric estimations are used to verify theoretical models derived from the thermodynamic relations of the gas turbine. (C) 2000 Elsevier Science Ltd. All rights reserved.
