Abstract : An investigation is made into the effect on mean-squared error, as a performance measure in a single-axis compensatory tracking task, due to changes in the shape of the input power spectral density. Quasi-linear describing function theory is used to predict normalized mean-squared error with the pilot-vehicle dynamics represented by the crossover model. A digital computer program is used to evaluate the resultant mean-squared integrals and to plot normalized mean-squared error as a function of input and crossover model parameters. The effect on human operator performance due to an added low-amplitude high frequency extension to a near-rectangular input spectrum is studied. (Author)
