20.500.12556/DKUM-62253 REGULACIJA KOTNE HITROSTI ELEKTRO-HIDRAVLIČNEGA ROTACIJSKEGA SERVO-SISTEMA Z INDUSTRIJSKIM KRMILNIKOM CLOSE-LOOP ANGULAR VELOCITY CONTROL OF ROTATIONAL ELECTRO-HYDRAULIC SERVO-SYSTEM WITH AN INDUSTRIAL CONTROLLER V sklopu diplomskega dela smo se ukvarjali s posodobitvijo regulacijskega sistema hidravličnega motorja. Namen dela je bil zamenjati analogni regulacijski sistem s sodobnim industrijskim krmilnikom Siemens S7 1200 in nato izvesti regulacijo kotne hitrosti hidravličnega motorja. Tega smo se lotili z analizo sistema in njegovega delovanja. V namen določitve tipa regulatorja smo izvedli analizo stabilnosti in izrisali Bodejev diagram. Prav tako smo naredili matematični model in blokovno shemo v Simulinku za simulacijo dinamičnega obnašanja, s pomočjo katere smo določili parametre regulatorja. Preden smo regulator uporabili na realnem sistemu, smo njegovo delovanje preverili s simulacijo. As part of the thesis we have dealt with the modernization of a close-loop control system of a hydraulic motor. The purpose of the work was to replace the existing analog close-loop control system with a modern industrial controller Siemens S7 1200 and to perform a close-loop angular velocity control of the hydraulic motor. We have tackled this with analysing the system and it's mechanisms. To pick the right close-loop controller type we have conducted an analysis of the stability and have drawn the Bode plot. Furthemore we have made a mathematical model and a block diagram in Simulink where we have simulated the dynamic behavior of the system, through which we have picked the controllers parameters.. Before we have used the close-loop controller on the physical system, we have tested it with the help of the simulation. simulacija regulacija hidravlični motor Siemens S7 1200 simulation close-loop control hydraulic motor Siemens S7 1200 true true false N.
