The study focuses on the parameter and non-linear effects of the converter. Taguchi method has been applied to investigate the system model parameters' influences on the maximum average power output. ANSYS AQWA is employed to obtain the hydrodynamic parameters for calculating the output power. Both linear and non-linear dynamic models of the two-body wave energy converter will be analysed and simulated in bot..View full abstract
