The wave energy converter (WEC) devices provide access to a renewable energysource. Developing control strategies to harvest maximum wave energy requiressolving a constrained optimal control problem. It is shown that singularcontrol arcs may constitute part (or the entire) of extremal trajectories.Characterizing the optimal control structure, especially with the possibilityof many switches between regular and singular control arcs, is challenging dueto lack of \textit{a priori} information about: 1) optimal sequence as well asnumber of the regular and singular control arcs, and 2) the correspondingoptimal switch times (from a regular to a singular arc and vice versa). Thisinvestigation demonstrates the application of a recently developed construct,the Epsilon-Trig Regularization Method (ETRM), to the problem of maximizingenergy harvesting for a point-absorber WEC model in the presence of controlconstraints. Utility of the ETRM for the WEC problem is demonstrated bycomparing its high-quality results against those in the literature for a numberof test cases.
