Abstract

U završnom radu analizirala se stabilnost zatvorenog regulacijskog sustava s čovjekom u petlji. Sustav koji je promatran sastoji se od procesa (daljinsko upravljanje ronilicom), čovjeka regulatora i pojačanja regulacijskog odstupanja ispred regulatora. U radu je opisana prijenosna funkcija čovjeka te povijest istraživanja iste. Apsolutna stabilnost sustava provjeravana je Nyquistovim kriterijem za rubne vremenske konstante prijenosne funkcije čovjeka, te je određeno maksimalno pojačanje regulacijskog odstupanja za koje je sustav stabilan. Također, provedena je simulacija za različita pojačanja regulacijskog odstupanja te su dobiveni odzivi analizirani i komentirani.

Abstract (english)

The task is to analyse stability of closed loop regulation with the human in the loop. System consists of process (yaw control of the remotely operated underwater vehicle), human regulator and error amplifier in front of the regulator. Transfer function of a human and its history of research is described. Absolute stability of the system is tested by using Nyquist criteria for the edge time constants of the transfer function of the human and the max error amplifier for which the system is stable, is also determined by the Nyquist criteria. Furthermore, simulation for different error amplifier is conducted and results are analyzed and commented.
