20.500.12556/DKUM-46241 DOLOČANJE REGULACIJSKIH PARAMETROV REAKCIJSKEGA SISTEMA RC1 DETERMINATION OF CONTROL PARAMETERS FOR RC1 REACTION SYSTEM V diplomskem delu opisujemo določanje vrednosti regulacijskih parametrov reakcijskega kalorimetra RC1e Mettler Toledo in reaktorskega sistema EasyMax 102 Mettler Toledo. Parametre smo določali z metodo po Ziegler-ju in Nichols-u. Ta metoda temelji na regulacijskem sistemu brez povratne zanke. Vrednosti za povratno zanko smo izračunali z Excelovim diagramom, s katerim smo izračunali P in I regulacijska parametra. Reaktor RC1e smo uporabili za poskuse z večjimi volumni, medtem ko EasyMax za tiste z manjšmi. Oba reakcijska sistema sta avtomatizirana, kar pomeni, da računalnik sam regulira podane veličine. Poskuse smo izvajali pri različnih temperaturah, vrtilnih hitrostih mešala, volumnih in različnih gostotah medija. Dobljene vrednosti regulacijskih parametrov smo prikazali grafično v odvisnosti fizikalnih sprememb v sistemu. Ugotovili smo, da je P parameter odvisen od vseh prej omenjenih fizikalnih sprememb, medtem ko I parameter ni odvisen od vrtilne hitrosti mešala v reakcijski zmesi. Z reakcijo nevtralizacije smo preverili vpliv vrednosti regulacijskih parametrov na temperaturni odziv ter določili entalpije nevtralizacije. Dokazali smo, da so bili regulacijski parametri pravilno določeni, saj je bil odziv sistema brez osciliranja temperature v reaktorju, hkrati se je temperatura hitro vzpostavila na željeno vrednost. This dissertation is concerned with determining values of regulatory parameters for the reactor calorimeter RC1e Mettler Toledo and reactor system EasyMax 102 Mettler Toledo. Values of parameters were obtained using Ziegler and Nichols methods. The later relies on regulatory configuration without feedback loop. Values for the feedback loop were therefore calculated using Excel diagram, from which P and I regulatory parameters were obtained. RC1e reactor was used for large-volume experiments, while EasyMax was utilised for experiments in smaller volumes. Both systems were automated, meaning all provided values were computer regulated. Experiments were carried out at different temperatures, mixing velocities and volumes, as well as with mediums of varying densities. Experimental values of regulatory parameters were consequently plotted against physical changes in the system, providing us with the final results. We discovered that P parameter depends on all previously listed physical factors, whilst I parameter does not depend upon mixing velocity of the reaction mixture. By performing neutralising reaction, we determined the effect of regulatory parameter values over the temperature response and by doing so, we defined neutralisation enthalpy. With this we confirmed that previously determined regulatory parameters were correct, as the system quickly established the set temperature and the temperature did not oscillate during the operation. reaktor RC1e reaktor EasyMax 102 regulacijski parametri kalorimeter nevtralizacija. reactor RC1e reactor EasyMax 102 regulation parameters calorimeter neutralisation. true true false [S.
