Preferred frequency responses to oscillatory inputs in an electrochemical cell model:Linear amplitude and phase resonance

摘要

We investigate the dynamicmechanisms of generation of amplitude and phase resonance in a phenomenologicalnelectrochemical cell model in response to sinusoidal inputs.We describe how the attributes of the impedance andnphase profiles change as the participating physicochemical parameters vary within a range corresponding to thenexistence of stable nodes and foci in the corresponding autonomous system, thus extending previous work thatnconsidered systems close to limit cycle regimes. The method we use permits us to understand how changes innthese parameters generate amplifications of the cell’s response at the resonant frequency band and captures somenimportant nonlinear effects.
