摘要：
A new approach for time-delay identifcation is proposed in linear controlled systems.The delay is derived from the control loop in the system.The frequency-response function of the system is presented in terms of the impedance matrix.It is proved that the inverse form of the function may be expressed in the harmonic function,which is used to ft those data from the experiment.As an example,an isolator with the delayed feedback control is schemed to acquire such data.Using least square algorithm yields that the identifed delay can reach any required accuracy.
