Non-linear simulation of a wave energy converter with multiple degrees of freedom using a harmonic balance method
Computationally efficient simulation methods for wave en-ergy converters (WECs) are useful in a variety of applica-tions. The simulation task is particularly challenging when non-linearities are present in the WEC model. Using a Fourierprojection of the system inputs and variables, harmonic bal-ance...
