Three tuned, convergent identification algorithmswhich compute a model and an 1, error bound fromthe impulse response experimental data, are presented.Two are tuned to the measurement noise bound, whichin practical cases, is well known. The third one isasymptotically optimal and is tuned to the a priori informationon both, the system and the noise. Theseprocedures are applied to the identification of a Taylor-Couette hydrodynamic instability process, which is essentiallyan infinite dimensional problem
