Abstract

Izvajanje proporcionalne in servohidravlike, kjer obravnavamo odprtozančno in zaprtozančno krmiljenje poti hidravličnega valja, se trenutno izvaja na sistemu, ki ga krmilimo s programskim orodjem NI Labview in zunanjo enoto didaktičnega krmilnika PID. Tak sistem je namenjen osnovnemu izobraževanju študentov, medtem ko bi želeli študente izobraziti tudi na področju industrijske proporcionalne in servohidravlike. Naloga predstavlja izdelavo industrijskega hidravličnega krmilja z uporabo novega industrijskega krmilnika in razvoja nove podobe grafičnega vmesnika z uporabo programa TwinCAT 2. Najprej smo postavili nov koncept hidravličnega krmilja, vključno z industrijskim krmilnikom PLK CX9020 in pripadajočimi moduli za krmiljenje in zajem merjenih veličin. Ustrezno smo priključili proporcionalni ventil in vse senzorje. Potem smo v programskem okolju TwinCAT 2 razvili in izdelali grafični vmesnik, s katerim lahko izvajamo zaprtozančno krmiljenje. Vmesnik nam omogoča nastavitev členov PID, nastavitev začetne in končne pozicije hidravličnega valja ter prikazovanje osnovne veličine sistema, kot so tlaki in pomik hidravličnega valja. V okviru eksperimentov smo izvedli osnovno testiranje sistema po Ziegler-Nicholasovi metodi, katere rezultat so ustrezni parametri krmiljenja PID za doseganje stabilnega odziva sistema.

Secondary title:	Development and production of a graphical interface in the TwinCAT 2 environment for controlling hydraulic cylinder path
Secondary abstract:	The implementation of proportional and servo-hydraulic, where the open-loop and closed-loop control of the hydraulic cylinder path is threaten currently performed on a system controlled by the NI Labview software tool and external unit of the educational PID controller. This system is intended for general students education, while the desire is to educate students in the field of industrial proportional and servo-hydraulic. The task is to build an industrial hydraulic control unit using a new industrial controller and to develop a new graphic interface using TwinCAT 2. First, we have to set up a new hydraulic steering concept, including the CX9020 industrial PLC controller and associated modules for control and measuring quantities. The proportional valve and all sensors were connected correctly. Furthermore, in the TwinCAT 2 programming environment, we have developed and produced a graphical interface which can perform closed-loops. On the interface, we can adjust the PID parameters and the start and end position of the hydraulic cylinder and show fundamental system values such as pressures and displacement of the hydraulic cylinder. As part of the experiments, we performed testing of the system according to the Ziegler-Nicholas method, which resulted in the corresponding PID control parameters to achieve a stable system response.
