Neželene vibracije mehanskih sistemov so v inženirski praksi med najbolj obravnavanimi problemi. Kadar zahteve presežejo sposobnosti pasivnih metod, uporabimo aktivne. V tem delu je predstavljen razvoj aktivnega sistema za umiritev mehanskih nihanj z uporabo PID krmilnika in dvosmernega solenoida. V okviru tega je za izbran sistem izpeljana diferencialna enačba gibanja in zasnovan numerični model v programskem jeziku Python. V nadaljevanju je predstavljena zasnova elektronskega vezja za poganjanje dvosmernega solenoida za aktivni nadzor. S pomočjo numerične analize je izvedena študija parametrov takega sistema in prikazane omejitve z vidika aplicirane sile. Predstavljen je tudi postopek izdelave in preizkušanja fizičnega vezja in solenoida. Unwanted vibrations of mechanical systems are among the most studied problems in engineering. When passive methods are not sufficient, we resort to active control methods. In this thesis, the development of such an active system using a PID controller and a bidirectional solenoid actuator is presented. In this scope, the equations of motion for the selected system are derived, and a numerical model is designed using the Python ecosystem. The design process of the electrical circuit, used to drive the bidirectional solenoid is shown. Using the numerical model, a study of the system parameters was conducted and limitations regarding applied force were shown. The process of building and testing of the physical circuit and solenoid is also presented. |
