Abstract
In this study, we develop a model of workload as a function of task di fficulty. Experiments on compensatory tracking tasks are used to asses s the task difficulties. First, second, and third order plants that ar e controlled under three damping frequencies, no oscillation, critical ly damped, and overdamped, are investigated. The task difficulty index is defined as the ratio of root means square of path error to the roo t means square control velocity.
