[en] High-gain observer ; Distillation Column ; continuous-discrete observer
[en] In this paper we present a high-gain observer implemented in its discrete and
continuous-discrete versions in order to compare the performance of both algorithms. The
comparison is made considering the sampling time used to perform the observer’s correction
stage in order to establish that the continuous-discrete observer is the best option when a
low sampling time is used. Under this condition the continuous discrete observer can process
data performing a reliable on-line estimation of the system (a slow dynamics of the process
is required). We apply both algorithms to a distillation column that uses the Ethanol-Water
binary mixture.
