| contents | This research paper explores the potential of nonlinear magnetic levitation systems for energy harvesting by developing a modified system that incorporates a more realistic energy harvesting circuit, enabling a better representation of practical operating conditions. Methodologically, approximate solutions for the system dynamics were obtained using the method of multiple scales, complemented by numerical simulations to capture parameter variations visualized through phase planes and parameter variation plots. The results demonstrate that by adjusting capacitance to induce internal and primary resonances, an extended detuning formulation (utilizing parameters sigma3 and sigma4) is innovatively introduced to capture the coupled dynamic interaction between the harvesting circuit and the mechanical system under diverse conditions. Periodic variations in circuit charge and intermediate magnet dis placement were thoroughly analyzed. Comparisons with legacy models demonstrate that the proposed coupling mechanism effectively suppresses undesirable nonlinear behaviors, such as chaos and multi-stability, resulting in a more stable and predictable energy harvesting process. Ultimately, a critical trade-off between energy harvesting efficiency and dynamical stability is identified, providing a valuable new design perspective for practical energy harvesting systems. |
