- СтавкаANALYZING AND OPTIMIZING PI CONTROLLER METHODS FOR TWO TANK SYSTEM: A LABORATORY-BASED STUDY(Mašinski fakultet, Univerzitet Istočno Sarajevo, 2024-11) Rajaraman, Janani; Prodanović, Saša; Chittaluri, Sai Phani Chandra; Dubonjić, Ljubiša; Stojanović, Vladimir; Marković, Biljana; Milutinović, Miroslav; Milić, DavorThis research paper presents a comprehensive investigation into the design, analysis, and optimization of Proportional-Integral (PI) controller methods for interacting systems, conducted through laboratory experimentation. The study aims to enhance the performance and stability of PI controllers by exploring various tuning methods and strategies tailored to address the intricacies of interacting systems. Through a series of experimental setups in the laboratory environment, different PI controller tuning techniques are systematically evaluated, including modern optimization algorithms such as Genetic Algorithms, Particle Swarm Optimization and Ant Colony Optimization. The effectiveness of each tuning approach is assessed based on key performance metrics, including settling time, overshoot and steady-state error. Furthermore, the study investigates the robustness of the optimized PI controllers against parameter variations and disturbances commonly encountered in real-world systems. Comparative analysis and statistical evaluation are employed to identify the most suitable tuning method for achieving robust and reliable control performance in interacting system.
- СтавкаOPTIMAL CONTROL OF A TWO-WHEELED SELF-BALANCING MOBILE ROBOT BASED ON ADAPTIVE DYNAMIC PROGRAMMING(University of East Sarajevo, Faculty of Mechanical Engineering, 2024-11) Stojanović, Vladimir; Đorđević, Vladimir; Dubonjić, Ljubiša; Prodanović, Saša; Marković, Biljana; Milutinović, Miroslav; Milić, DavorThis paper considers optimal tracking control for a two-wheeled selfbalancing mobile robot with unknown dynamics. The aim is to achieve asymptotic tracking and disturbance rejection by minimizing some predefined performance index. Through the combination of adaptive dynamic programming (ADP) and internal model principle, an approximate optimal controller is iteratively learned online using measurable input/output data. Unmeasurable states are also reconstructed from input/output data. The discrete-time algebraic Riccati equation is iteratively solved by ADP approach. Simulation results demonstrate the feasibility and effectiveness of the proposed approach.
- СтавкаVodovodni sistemi i cirkularna ekonomija(Union of Engineers and Technicians of Serbia, Belgrade, 2024) Orašanin, Goran; Marinović, Budimirka; Đukić, AleksandarПримјена циркуларне економије у водоводним системима се у последње вријеме све више истражује. Врше се конкретни експерименти као и практична примјена у индустрији са циљем уштеде трошкова, производње енергије те производње материје и енергије из процеса третмана отпадних вода. С тим у вези, овај рад има за циљ да идентификује неке од мјера које водоводна предузећа могу предузимати у циљу одрживости и смањења утицаја на животну средину. У раду је дат кратак преглед могућности водоводног предузећа крод дјеловање на воду, материју и енергију.
- СтавкаTEHNIČKI ASPEKTI KORIŠĆENJA OKLASKA KUKURUZA ZA DOBIJANJE TOPLOTNE ENERGIJE(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije, Društvo za procesnu tehniku, 2024) Simić, Stojan; Milić, Davor; Orašanin, Goran; Karličić, Nikola; Obradović, Marko; Stanojević, Miroslav; Jovović, AleksandarU poljoprivredi postoje velike količine biljnih ostataka koje se mogu koristiti za proizvodnju energije.Poljoprivrednu biomasu čine ostaci jednogodišnjih kultura kao što su: slama žitarica, ku-kuruzovina, oklasak kukuruza, stabljika, ljuska, koštice i dr. Oklasak kukuruza je nusproizvod koji nastaje prilikom korišćenja kukuruza. U radu se sa više aspekata razmatra upotreba kukuruznog oklaska kao goriva u pećima i kotlovima. Provedena istraživanja pokazuju da je primena ovog otpad-nog materijala prihvatljiva sa više aspekata za proizvodnju toplotne energije.
- СтавкаCOMPARING THE ACCURACY OF MASTER MODEL AND THEIR REPLICAS PRODUCED BY RAPID TOOLING USING VACUUM CASTING(Mašinski fakultet, Univerzitet u Banjoj Luci, 2019) Kraišnik, Milija; Ilić, Jovica; Jotić, Goran; Mačkić, Tihomir; Anić, Jelica; Gvero, Petar; Prochaska, BiljanaIn this paper we compared the accuracy of an original master model which was used to make the silicone mold and mold cavity and its replicas obtained by the vacuum casting technology. This technology allows us to create small batches of parts based on the master model in a relatively short time. The aim of the paper is to compare the accuracy of replicas produced with the OEM part using a reversible engineering technique, that is, CAD to part.
