Abstract. In this paper, an implementation of variable structure
system (VSS) with proportional-plus-integral (PI) term in the synthesis
of model reference adaptive control (MRAC) is presented. Two algorithms
which synthesize the signal adaptation, whose integral term in the control
ensures minimal value of the error between the reference model and the
plant, have been considered. The stability proof of these systems is obtained
via VSS theory. The performances of the proposed MRACs are evaluated and
shown by means of digital simulation.
Key words: variable structure systems, model reference adaptive
control, signal adaptation.
ADAPTIVNI
SISTEMI SA REFERENTNIM MODELOM PROMENLJIVE STRUKTURE SA PROPORCIONALNI-INTEGRALNIM
DELOVANJEM
U ovom radu je predstavljena primena sistema
promenljive strukture (SPS) sa proporcionalno-integralnim (PI) članom u
sintezi adaptivnih sistema sa referentnim modelom (ASRM). Razmatrana su
dva algoritma koji sintetišu signalnu adaptaciju i čije integralno dejstvo
obezbeđuje minimalnu vrednost greške između izlaza referentnog modela i
objekta. Dokaz stabilnosti ovih sistema je dobijen preko teorije SPS. Osobine
predloženih ASRM-a su izvedene i prikazane korišćenjem digitalne simulacije.
