Output intersampling approach to direct closed-loop identification
A new direct closed-loop identification method, which uses the output intersampling technique, is proposed in this note. By using the intersampled plant input-output data, the proposed method removes the traditional restrictive Identifiability condition, and does not require an external persistently exciting (PE) test signal.
