In this paper an identification procedure for linear constant coefficient systems is proposed. If an appropriate mathematical model for the system to be identified is made, the parameters of the model can be determined from the functions of the exponentially weighted time integrals of the input and output of the system or from those of the correlation functions. These functions are equal to the coefficients of the Taylor series expansion of the inverse tansfer function of the system about s=α(α≥0).
This method can also be applied to comparatively complicated systems such as the closed control system, because the coefficients of the Taylor series expansion of the inverse transfer function of the system are relatively simple if compared with those of the transfer function of the system used in the modified moment method.
The efficiency of this method is demonstrated by the digital simulations for two examples.
