Abstract
Azimutni porivnik se može zakretati za puni krug i pritom razvijati poriv u svim smjerovima. Područje poriva azimutnog porivnika opisuje se krugom čiji radijus predstavlja maksimalni poriv tog porivnika. Zabranjene zone rada porivnika su područja u kojima poriv ne smije biti alociran. Budući da je ukupno područje poriva azimutnog porivnika opisano krugom, zabranjene zone su kružni isječci. Na ovaj način područje poriva sa zabranjenom zonom rada porivnika poprima tzv. Pacman oblik. Zabranjene zone uvode se kako bi se spriječilo štetno međudjelovanje porivnika ako su porivnici smješteni blizu jedan drugome ili bi razvijanje poriva u zabranjenoj zoni onemogućilo pravilan rad mjernih uređaja za određivanje pozicije plovnog objekta i sl. Zabranjene zone postavljaju se u obliku ograničenja u algoritme za alokaciju poriva. U radu je obrađena metoda kvadratičnog programiranja gdje je zabranjena zona postavljena u obliku nejednadžbi i kao takva implementirana u optimizacijsku zadaću.
Abstract (english)
Azimuth thruster can turn a full circle and in that way can develop thrust in all directions. The thrust region of azimuth thruster is described with a circle whose radius represents the maximum thrust. The forbidden zones are sectors in which the thrust must not be allocated. Because the total thrust region of azimuth thrusters is described by the circle, forbidden zones are represented by circular clips. Due to that, the thrust area with forbidden zone takes so called Pacman form. The forbidden zones are implemented to prevent harmful thruster-thruster interference, if the thrusters are located close to each other, or because of that the developed thrust would prevent the appropriate functioning of the hydroacoustic positioning systems etc. The forbidden zones are set in the form of constraints in the algorithms for the thrust allocation. In this thesis the method of the quadratic programming was elaborated where the forbidden zone has been described with inequality constraints, and in that way implemented in the optimization task.
