Abstract
With more focus on multiple-degree-of-freedom wave energy converters, the tools needed to analyze these dimensions properly must expand accordingly. This paper uses Floquet theory to examine the parametrically excited pitch-surge modes and a numerical solver to determine the system's stability. It then shows how control methods and coupling affect this stability. The findings demonstrate that the coupled system has regions of instability close to linear resonance and parametric excitation frequency ratios which significantly affect the wave energy converter's ability to produce power.
