PROCESS SIMULATOR FOR EXPERIMENTAL CONTROL SYSTEM DESIGN WITH LabView

Diplomsko delo obsega izdelavo simulatorja industrijskega procesa v programskem okolju LabView za načrtovanje parametrov PID regulatorja. Predstavljena je programska oprema LabView v kateri je izdelan model sistema tlačnih posod do dinamike 3. reda, ki zajema lastnosti in posebnosti procesnih elementov (ventili, črpalke). Povezava simulatorja z industrijskim krmilnikom OMRON CJ1G je izvedena z ADDA kartico NI USB6008. Prikazano je praktično spoznavanje oziroma testiranje te strojne opreme. Opisan in slikovno prikazan je postopek izdelave simulacijskega modela v programskem okolju LabView. Na koncu je opisano praktično načrtovanje parametrov PID regulatorja, po metodi Ziegler-Nichols in primerjava delovanja simulatorja z rezultati dobljenimi na realnem procesu.Diploma paper involves development and design of an industrial process simulator realized by the LabView software intended for PID control design. The LabView software is presented where a model of pressure tanks is modeled up to the 3rd order dynamics and properties of typical elements used in automation (valves, pumps) are modeled. Data communication between simulator and industrial controller OMRON CJ1G was made by ADDA card NI USB 6008. Hardware and software used in the diploma paper are presented along with configuration and tested on laboratory model. Implementation of simulation process model in the LabView is thoroughly described with instructions for operation. At the end a simple experimental design of PID controller parameters was carried out on the real process, by the Ziegler-Nichols recommendation, where results were compared to the simulator output results
