  Intermittent control has a long history in the physiological literature and
there is strong experimental evidence that some human control systems are
intermittent. Intermittent control has also appeared in various forms in the
engineering literature. This article discusses a particular mathematical model
of Event-driven Intermittent Control which brings together engineering and
physiological insights and builds on and extends previous work in this area.
Illustrative examples of the properties of Intermittent Control in a
physiological context are given together with suggestions for future research
directions in both physiology and engineering.
