Abstract
This paper extends the authors' previous method on linear system identification which is independent of the dynamics of the measuring devices used for observing the input-output signals of the object system. The essence of the method lies in the double measuring concept to generate the suitable input-output data for identification by means of the convolution integral of a different pair of input-output signals obtained through double measurements.
The following extension and discussion are given in this paper:
1) the method is extended to be applicable to the linear system whose input-output signals are different kinds of physical quantities; and
2) another method is examined of using the observed input-output signals obtained through double measurements, which conducts the conventional identification procedure twice, to be feasible.
