Output error identification algorithms for continuous-time systems operating in closed-loop

This paper presents off-line and recursive output error identification algorithms for linear continuous-time systems operating in closed-loop from sampled data. The resulting algorithm can be considered as the continuous-time version of the Filtered Closed Loop Output Error (F-CLOE) identification method for discrete-time systems proposed by Landau. Simulations results and the application of the proposed strategy to an experimental liquid level control system are also presented.
