A Methodology for the Identification of Helicopter Mathematical Models From Flight Data Based on the Frequency Domain

[摘要] There is considerable need for the application of system identification techniques to helicopters. These include their use in the validation and improvement of existing theoretical flight-mechanics models, and for development flight testing. In both cases, estimates of stability and control parameters are sought. Most applications of system identification techniques to helicopters have involved time-domain methods which use reduced-order mathematical models representing six-degrees-of-freedom rigid-body motion. In this document, an identification methodology which uses the frequency-domain to obtain estimates of the stability and control parameters is advocated.
