摘要：

In this paper the orthogonal estimation algorithm is used to estimate a NARMAX model for an aircraft gas turbine. The performance of the model is validated using a range of small and large signal tests and by examining the model's static and dynamic characteristics. The NARMAX representation allows the direct mapping to the frequency domain by computing the Higher Order Frequency Response Functions (HOFRF) thus allowing physical interpretation to be made.
