Abstract

The auto-correlation and cross-correlation of a nonlinear stochastic energy harvesting system are studied by stochastic simulation method, which show periodic oscillation and gradual attenuation, implying that the nonlinear stochastic energy harvesting system possesses complex dynamical behaviors. Among correlations of the dynamical variables, the cross-correlation strength of system variables x and V is largest, which possess the important effect on the system output. The coupling coefficient of the voltage , the capacitance coupling constant , and the time constant , enhance the strength of system correlations, and increase the system output. However, the roles of the viscous coefficient γ and the noise strength D is just opposite, decrease the system output and increase the output stability of the system.
