Methods for allocating redundant controls for systems with four or more objectives are studied. Previous research into aircraft control allocation has focused on allocating control effectors to provide commands for three rotational degrees of freedom. Redundant control systems have the capability to allocate commands for a larger number of objectives. For aircraft, direct force commands can be applied in addition to moment commands. When controls are limited, constraints must be placed on the objectives which can be achieved. Methods for meeting commands in the entire set of of achievable objectives have been developed. The Bisecting Edge Search Algorithm has been presented as a computationally efficient method for allocating controls in the three objective problem. Linear programming techniques are also frequently presented. This research focuses on an effort to extend the Bisecting Edge Search Algorithm to handle higher numbers of objectives. A recursive algorithm for allocating controls for four or more objectives is proposed. The recursive algorithm is designed to be similar to the three objective allocator and to require computational effort which scales linearly with the controls. The control allocation problem can be formulated as a linear program. Some background on linear programming is presented. Methods based on five formulations are presented. The recursive allocator and linear programming solutions are implemented. Numerical results illustrate how the average and worst case performance scales with the problem size. The recursive allocator is found to scale linearly with the number of controls. As the number of objectives increases, the computational time grows much faster. The linear programming solutions are also seen to scale linearly in the controls for problems with many more controls than objectives. In online applications, computational resources are limited. Even if an allocator performs well in the average case, there still may not be sufficient time to find the worst case solution. If the optimal solution cannot be guaranteed within the available time, some method for early termination should be provided. Estimation of solutions from current information in the allocators is discussed. For the recursive implementation, this estimation is seen to provide nearly optimal performance. / Ph. D.

<p>U ovom radu testirane su pretpostavke Op&scaron;teg modela agresije o činiocima koji utiču na javljanje agresivnog pona&scaron;anja. Osnovni cilj istraživanja bio je ispitivanje efekata osobina ličnosti i nivoa situacione provokacije na agresivno pona&scaron;anje. Pri tome, ispitivao se i njihov efekat na pristrasnosti u pažnji i emocionalno stanje, koji predstavljaju važne činioce u oblikovanju agresije. Na uzorku od 226 studenata primenjeni su inventar ličnosti HEXACO&ndash;PI&ndash;R i upitnik agresivnosti BODH. Nekoliko nedelja nakon popunjavanja upitnika, ispitanici su učestovali u takmičarskim zadacima brzine reakcije s ciljem indukcije i merenja agresivnog pona&scaron;anja. Ispitanici su slučajnim redosledom bili raspoređeni u jedan od četiri uslova manipulacije koji odgovaraju različitim nivoima situacione provokacije. Nakon uče&scaron;ća u takmičarskim zadacima, ispitanici su popunjavali upitnik stanja afekta, pa su potom učestovali u emocionalnom Strupovom zadatku. U tom zadatku merene su pristrasnosti u pažnji na agresivne, prijatne i neutralne stimuluse. Rezultati pokazuju da uslovi manipulacije nisu ostvarili efekat na agresiju, ali jesu na promenu u agresivnom pona&scaron;anju tokom uče&scaron;ča u zadacima u okviru visokoprovokativnog i niskoprovokativnog uslova. Agresija u visokoprovokativnom uslovu se povećavala kako procedura odmiče, a u niskoprovokativnom uslovu se smanjivala. Od osobina ličnosti, po&scaron;tenje (HEXACO) i osvetoljubivost (BODH) ostvarili su dosledne efekte na agresiju, nezavisno od uslova. Efekti emocionalnosti, savesnosti i otvorenosti, kao i dimenzije agresivnosti &ndash; hostilnost, zavisili su od uslova provokacije ili dužine izloženosti provokaciji. U slučaju efekata na pristrasnosti u pažnji, rezultati su pokazali da se po&scaron;tenje povezuje s pristrasnostima prema agresivnim sadržajima, nezavisno od uslova. Savesnost i osvetoljubivost se takođe mogu povezati s pristrasnostima u pažnji, ali njihovi efekti na određene sadržaje pristrasnosti zavise od nivoa provokacije. Iako je stanje besa bilo povi&scaron;eno u visokoprovokativnom uslovu, u tom uslovu ono nije ostvarilo značajan medijatorski efekat u odnosu između osobina ličnosti i agresije, kao ni u odnosu između osobina ličnosti i pristrasnosti u pažnji, &scaron;to nije u skladu s Op&scaron;tim modelom agresije. Rezultati ukazuju na značaj interaktivnog pristupa prilikom ispitivanja člinilaca koji doprinose ispoljavanju agresije.</p>
