Abstract :
This paper deals with system identification of new system dynamics revealed by online introduction of new sensors in existing multi-variable linear control systems. The so-called ¿Hansen Scheme¿ utilises dual Youla-Kucera parameterisation of all systems stabilised by a given linear controller to transform closed-loop system identification problems into open-loop-like problems. We show that this scheme can be reformulated to accomodate extra sensors in a nice way. The approach is illustrated on a simple simulation example.
