DESIGN AND REALIZATION OF PID CONTROLLER ON SIEMENS

V diplomski nalogi so predstavljeni analogni in digitalni regulatorji. Predstavljena je strojna in programska oprema krmilnikov Siemens serije S7-300 in S7-1500, natančneje sta predstavljena krmilnika S7-314 IFM in S7-1516-3 PN/DP, za katera so izvedene meritve hitrosti delovanja. V programskem jeziku Step 7 je za oba krmilnika napisana programska koda digitalnega PID regulatorja. Za preizkus delovanja izdelanih regulatorjev smo uporabili univerzalni simulator dinamičnih sistemov. Univerzalni simulator omogoča simulacijo prenosnih funkcij izbrane stopnje in izbranih parametrov. Narejen je na osnovi PC-ja in vhodno/izhodnega vmesnika MyDAQ s programsko opremo LabView.The thesis presents the analog and digital controllers. It describes the hardware and software of Siemens S7-300 series and S7-1500 series of controllers, highlighting the details of the S7-314 IFM and S7-1516-3 PN/DP controllers which were also checked for the operation speed. For both of the controllers, the programming language Step 7 was used to write the programming code of the digital PID regulator. To test the operation of controllers, the universal simulator of the dynamic systems is used. The universal simulator is used to simulate the transfer functions of the selected rate and with the selected parameters. It is PC-based with the MyDAQ input/output interface and LabVIEW software
