摘要
A method for characterizing a nonlinear system using the system's steady state response including: exciting a transducer using a plurality of frequencies while decoupled from the nonlinear system, measuring the amplitude of response of each of the frequencies while decoupled from the nonlinear system, exciting the transducer using the plurality of frequencies while coupled to the nonlinear system, measuring the amplitude of response of each of the frequencies and the second harmonic of at least some of the frequencies, and solving for a set of phenomenological parameters characterizing the dynamics of the nonlinear system.
