Abstract :
A genetic algorithm (GA) based method to derive a reduced order (rth order) model for a given stable discrete-time system is presented. In this method not only stability is preserved and the first r time moments/Markov parameters are fully retained but also the errors between a set of subsequent time moments/Markov parameters of the system and those of the model are minimized. Furthermore, the operations of the proposed method are carried out entirely in z domain
