A study was made of describing function models of human trackers while operating control systems with Gaussian plus step inputs. The parameters in the describing function model were adjusted using existing parameter adjustment rules and experimental data. Four performance measures were determined from the experimental data to assess their usefulness in adjusting the parameters of human pilot describing function models. The experiments were run using three subjects with varied levels of flying experience. Each subject was given the single task of controlling a system with one of three different controlled elements K, KS, KS squared. Data were collected on each subject for each system with a single step input, Gaussian input, and Gaussian plus step input. Comparisons of the output of the piloted systems and the model systems were made, and suggestions for applications to the controlled element dynamics were offered.
