Popis:	This paper provides a method for obtaining a continuous-time model of a target system in a closed-loop environment from input-output data alone. The proposed method is based on a fixed-pole observer model, which is a reasonable continuous-time version of the innovation model in discrete-time and allows the identification of unstable target systems in closed-loop environments with unknown controllers. The method is within the framework of the stabilized output error method and shares usability advantages such as robustness to noise with complex dynamics and applicability to a wide class of models, in addition to advantages derived from continuous-time models such as tolerance to system stiffness and easy access to physical knowledge. The effectiveness of the method is illustrated through numerical examples. Comment: 6 pages, 7 figures
