Abstract

In the following report it is described how a routine implemented in the Matlab software package is used for identifying the stability derivatives of a gyroplane. The software is designed to apply a frequency domain least squares approach in order to estimate the longitudinal and lateral force and moment derivatives of the aircraft. The aircraft system itself is represented as a linear state space model. The time histories of the system states in conjunction with the pilot input are analysed in order to perform the identification. Initially the time series are transformed into the frequency domain. Linear regression is then performed over a suitable frequency range and an estimate of the stability derivatives together with the corresponding standard errors, is produced. The method is applied and tested against real data obtained from research conducted in the past within the department.
