  • Publication number: 20210010980
    Abstract: A system identification device 1 includes an analysis unit 105 that calculates a self-frequency response function on the basis of an input signal and an output signal measured by a measurement unit 103 at a position where a subject physical system 106 has been excited by a vibrating unit 102. The analysis unit 105 performs system identification of the subject physical system 106 by using an impulse response function obtained from the calculated self-frequency response function and an impulse response function of a virtual two-degrees-of-freedom model modeling the subject physical system 106 that is the subject of analysis. This makes it possible to perform system identification of systems with close eigenvalues.
