Abstract

V diplomskem delu smo preučevali regulacijo procesov prvega in drugega reda ob prisotnosti različno dolgih mrtvih časih in različni velikosti časovne konstante pri predpostavki, da regulacijske konstante določimo z algoritmom za samonastavitev regulatorja. V delu prikazujemo izdelavo simulacije nereguliranega procesa – odziva na stopničasto spremembo, simulacijo reguliranega procesa s povratno zančno regulacijo in postopek samonastavitve konstant regulatorja v program MATLAB / Simulink. Analiza je potekala na primerih generičnih proces prvega in drugega reda s povratno zančno regulacijo in PI ter PID regulatorjem. Namen diplomske naloge je bil ugotoviti, kateri tip regulacije je učinkovitejši pri odpravi motnje in sledenju referenčni vrednosti. Rezultati dela nakazujejo, da sta PI in PID regulaciji primerljivo učinkoviti pri regulaciji procesov prvega in drugega reda ob prisotnosti mrtvega časa. Algoritem za avtomatsko prilagajanje regulacijskih konstant poda vrednosti konstant, ki zagotavljajo učinkovito sledenje spremembi referenčne vrednosti. Prav tako zagotavljajo učinkovito odpravo motenj, ki se pojavi v procesu.

Secondary title:	Simulation and comparison of control mechanisms for control of processes with dead time
Secondary abstract:	In the thesis we have studied the control of first and second order processes in the presence of dead times of different lengths and different magnitudes of the time constant, assuming that the controller constants are determined by the autotuning algorithm. The work presents simulations of an uncontrolled process - response to a step change in input, simulations of a feedback-controlled process, and the autotuning procedure of the controller constants in MATLAB / Simulink. The analysis is performed on examples of generic first and second order processes with PI and PID feedback control scheme. The aim of the work was to determine which type of control is more efficient in eliminating the effects of disturbance and in tracking the changes in the setpoint changes. The results show that PI and the PID control are comparatively effective in controlling first and second order processes in the presence of dead time. The autotuning algorithm provides controller constants that ensure efficient tracking of the changes in the setpoint. They also ensure effective elimination of disturbances that occur in the process.
