Abstract:

The objective of this work was to determine, through a frequency analysis approach, an appropriate range of values for the parameters which could be used to provide for an effective auto-pilot coupler transfer function. The power spectral density function for random data, describing the general frequency composition of the data in terms of the density of its mean square value was used in this analysis. Spectral plots of data generated by a digital simulation were compared to those of an actual flight test case used as a reference to determine when the appropriate range has been found. In the development a spectral analysis program was written that incorporates the Cookey-Tukey fast Fourier transfer, allowing the conversion of the data sets from the time domain to the frequency domain. This resulted in a range of values for the parameters of gain and lead in two channels of a model of the human pilot operator in an attacker-evader simulation. Author
