Phase control has previously been proposed for increasing energy output from wave power devices, and latching strategies have been tested for point absorbers and for pneumatic devices. Theoretical studies to determine optimal control strategies have not, however, been carried out until now. This paper provides a framework for the analysis of the problem, based essentially on L. S. Pontryagin's Maximum Principle. It indicates stable computational techniques for finding optimal solutions and summarize the results of studies on two devices - a point absorber and an oscillating water column.
