摘要: In this paper, a simple scheme to estimate frequency responses of linear time-invariant single-input single-output (SISO) systems based on closed-loop step response data is investigated. The method uses only single set plants under operating conditions. input and output plant are filtered by bandpass filter, the obtained with Discrete Fourier Transforms (DFTs) signals. validity proposed illustrated through simulations experiments.
