Human Control Strategy: Definition
We define human control strategy as a reaction skill,
which, in terms of complexity, lies somewhere between low-level
feedback control and high-level reasoning. A particular control
strategy is not only defined by the "gains" or parameters in the
controller, but also the structure or approach of the
strategy. Consider the skill of driving a car, for example. The
diagrams below illustrate applied force profiles over the same road
for two different individuals in a driving
simulator. The distinction between the two driving styles is a
difference in kind rather than merely a difference in degree, similar
to the structural difference between a linear feedback and a variable
structure controller. Each represents a unique control strategy.
