摘要：

This paper shows that the plant impulse response can be estimated by the inverse discrete Fourier transform of the estimated plant frequency response that is the ratio of the discrete Fourier transforms of the prefiltered output and input of the plant, and it corresponds well with the estimated plant impulse response that is the plant output filtered by the inverse filter of the plant input. © 2020 The Institute of Electrical Engineers of Japan.
