Kinematic Characterization of Marine Wave Energy Devices Based on Immune Particle Swarm Algorithm

Abstract

This paper explores the optimization of motion characteristics and energy output in an ocean wave energy device. The displacement and velocity of the device in pendant oscillatory motion are explored by simplifying the device model and simulating it using Simulink. Numerical methods are employed to solve the dynamics model. Subsequently, an optimization model for the average output power of the damper is developed based on this exploration. Both the grid search method and particle swarm algorithm are utilized to optimize the damping coefficients. These two methods are compared, revealing the particle swarm algorithm's superior efficiency.
