We investigated the nonlinear dynamic behavior of the system for energy harvesting using ocean wave motion. The system consists of a linear electromagnetic system coupled to a float to move with ocean waves. We define the mathematical modeling of a structure together with the parameters for energy harvesting. In this way, we analyzed average power for the parameters linked to the wave profile, the resistance load of the electromechanical motor, and the nonlinear parameters of spring cubic. Therefore, we also analyze the nonlinear dynamic behavior with Maximum Lyapunov exponent, bifurcation diagrams, phase portraits, and Poincaré maps.

用于能量收集的海洋浮标非线性行为的动力学分析

我们研究了利用海浪运动收集能量的系统的非线性动态行为。该系统由一个线性电磁系统组成，该系统耦合到一个浮标，随着海浪移动。我们定义了结构的数学模型以及能量收集参数。通过这种方式，我们分析了与波形相关的参数、机电电机的电阻负载和弹簧三次方的非线性参数的平均功率。因此，我们还使用最大李雅普诺夫指数、分岔图、相图和庞加莱图分析非线性动力学行为。
