[R] R Help: System Identification for First order delay and dead time with TF model

[Yoshikazu Noguchi]

Hello,

 

May I ask your help?

 

I would like to do System Identification using time series data which has
transport delay. 

First of all, I would like to identify the following parameters (K, Tau, TD)
for SISO case in the following Laplace domain equation: 

K, Tau, TD:   ymodel = (K/(Tau*s +1)) * exp(-TD*s) 

I have time series data, y (Process output) and U (process input). 

 

Object function: Min ( (y-ymodel)^2) 

 

I failed to find the right package in R for this issue? Could you please
tell me which package I should use to solve this issue?

 

Thanks. 

 

Y. Noguchi
