Abstract

Tema ovog diplomskog rada je implementacije vanjskog sustava regulacije za prigušivanje torzijskih vibracija bušećeg vretena na programibilnom logičkom kontroleru (PLC). Prema matematičkom modelu i Matlab/Simulink modelima izrađen je program za FX5 PLC proizvođača Mitsubishi Electric. Prvi dio programa sadrži sustav za prigušivanje torzijskih vibracija, te virtualni model motora i frekvencijskog pretvarača. Nakon što je simulirani sustav pokazao dobre rezultate izrađen je eksperimentalni postav koji sadrži sustav prigušivanja torzijskih vibracija bušećeg vretena na programibilnom logičkom kontroleru, operatorski panel (HMI) te frekvencijski pretvarač kojim se upravlja motor. Kako bi se na motoru simulirale vibracije bušećeg vretena u frekvencijskom pretvaraču se koristi dodatni signal virtualnog okretnog momenta iz simulatora u realnom vremenu, a koji u sebi sadrži karakteristike torzijskih vibracija bušećeg vretena

Abstract (english)

This master’s thesis describes the implementation of the external drill-string drive torsional vibration damping system on a programmable logic controller (PLC). Based on the mathematical model and Matlab/Simulink models, a program was created for FX5 PLC manufactured by Mitsubishi Electric. The first part of the program contains a system for dampening torsional vibrations, as well as a virtual motor and a frequency converter. After the simulated system showed good results, an experimental set-up was created, which contains a programmable logic controller, an operator panel (HMI) and a frequency converter controlled by the motor. To simulate the vibrations of the drill-string on the motor, a virtual torque signal from the on-line simulator is supplied to the motor driver which has the characteristics of the drill-string torsional vibrations.
