A study on adjusting resonance frequency of a vibration power generation system by using variable capacitance and output power maximization by extremum seeking control

Abstract

By variable capacitance connected to a vibration power generation system, we can adjust its resonance frequency. Using numerical simulations, we first examine whose parameter is dominant to adjust the resonance frequency by changing variable capacitance. Then, we verify the effectiveness of extremum seeking control to maximize the output power of the vibration power generation system for a sinusoidal excitation force.
