A Coupled Analysis of Nonlinear Vibration Energy Harvester Based on Predictor-Corrector Approach

This paper presents a coupled analysis method for vibration energy harvesters based on predictor-corrector approach. To consider coupling of vibration and electromagnetic systems, time-evolutions of system states are predicted, and coupling factors are evaluated from the predicted states. Then, the next system states are evaluated by solving governing equations of the systems. From the predicted and computed states, coupling factors are corrected. It is shown that the proposed method can evaluate the performance of vibration energy harvesters with little computational burden, although the analysis results are almost equal to the conventional quasi-strong coupled analysis method. Moreover, measurement results show that the proposed method can qualitatively simulate behaviors of nonlinear vibration energy harvesters
