Abstract :
A new identification algorithm for a linear discrete-time closed-loop system is proposed based on an output over-sampling scheme. Even if the ordinary identifiability conditions are not satisfied, a closed-loop system can be identified by using the over-sampled output data which contain more information about the system structure without utilizing any external test signal. It is a distinctive advantage of the proposed approach compared to conventional ones
