Pre-identification for real-time control

Abstract

The paper deals with the algorithm named as pre-identification, which denotes the simple general identification algorithm used for the system identification. The identification is realized before the system is controlled. It can be used in case the controlled system is time-invariant or slightly time-variant. Furthermore, the identified system might be nonlinear. Pre-identification provides a priori system description which is necessary for switching self-tuning control or useful for nonlinear control. The verification of the pre-identification usefulness was realized on several laboratory apparatuses in real-time using PC. © 2009 Springer-Verlag Berlin Heidelberg.
