This chapter describes an approach to the problem of dynamic model identification of aero engines using frequency response techniques. A problem with frequency response identification is obtaining an optimal spectral resolution. A visual-analysis-based optimization technique for identification is proposed providing a compromise between the bias and variance of the spectral estimate. The accuracy of the identification is provided by the optimal choice of spectral resolution using a priori information about the engine dynamic model.
