Abstract
.U radu je prikazan utjecaj transportnog kašnjenja na kakvoću regulacije, te prikazana problematika projektiranja takvih sustava. Cilj ovog rada je prikazati kako transportno kašnjenje utječe na različite strukture upravljanja, te kako pronaći najbolje rješenje. Opisan je postupak projektiranja regulatora za procese s izraženim transportnim kašnjenjem. U radu je prikazan utjecaj transportnog kašnjenja na jednom realnom industrijskom procesu miješanja dviju različitih koncentracija tekućina. Izvršena je analiza procesa primjenom klasičnih metoda upravljanja s PI regulatorom, te prikazani rezultati odziva sustava na Step pobudu. Prikazano je kako klasične jednopetljasta regulacija ne zadovoljava takvim procesima, te da je potrebno pristupiti složenim strukturama upravljanja kao što su: Smithov prediktor i njegove varijante za povećanje robusnosti (PPI i FPPI), te predupravljanje. Smithov prediktor daje zadovoljavajuće rezultate, ali uvođenjem PPI i FPPI kakvoća regulacije se povećava. Rezultat diplomskog rada je kroz analizu prikazati i definirati rješenja upravljanja s transportnim kašnjenjem nad stvarnim industrijskim procesima.
Abstract (english)
The paper presents the impact of transport delays on the quality of regulation and presents the problems of designing such systems. This paper aims to show how transport delays affect different control structures, and how to find the best solution. The procedure for designing a controller for processes with a pronounced transport delay is described. The paper presents the influence of transport delay on a real industrial process of mixing two different concentrations of liquids. The process analysis was performed using classical control methods with a PI controller, and the results of the system-to-step response are presented. It is shown that classical single-loop control does not satisfy such processes and that it is necessary to approach complex control structures such as Smith's predictor and its variants for increasing robustness (PPI and FPPI), and pre-control. Smith's predictor gives satisfactory results, but with the introduction of PPI and FPPI the quality of regulation increases. The result of the diploma thesis is to present and define solutions for managing transport delays over real industrial processes through analysis.
