摘要：

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