Firstly, continuous-time model-based predictive control where the intermittency is associated with on-line optimisation.
Thirdly, explanation of physiological control systems which, in some cases, have an intermittent character.
Intermittent control initially evolved separately in the engineering and physiological literature.
Fernando Navas and James Stark[3] showed experimentally that human hand movements were synchronised to input signals rather than to an internal clock: in other words the hand control system is event-driven not clock-driven.
[4] A more recent mathematical model of intermittency is given by PeterGawthrop, Ian Loram, Martin Lakie and Henrik Gollee.
