Intermittent control, where a sequence of open-loop trajectories is punctuated by intermittent feedback, is described, and a number of design methods are presented. A generalized hold representation is derived and shown to be useful for both implementation and analysis. The relationship between predictive control of a time delay system and intermittent control is examined, and it is shown that a simplified predictor can be used in the latter case.The applicability of intermittent control to the implementation of model-based predictive control (MPC) is discussed and illustrated by the control of a difficult mechanical system -a self-balancing seesaw.
