dc.description.abstractPiezoelektrični aktuatori se uveliko primenjuju za aktivno upravljanje vibracijama na raznim strukturama sa ciljem povećanja performansi sistema. Razvijeni sistem aktivnog upravljanja vibracijama se sastoji od aktivnije strukture, kontrolera i visokonaponskih pojačivača. U ovom radu, kompozitna greda predstavlja osnovnu strukturu za senzorsku (merne trake) i aktuatorsku (dvoslojni PZT piezoelektrični aktuator) platformu. U cilju unapređenja dinamičkih karakteristika aktivnog sistema vršena je promena koeficijenata PID regulatora. Efikasnost sistema aktivnog upravljanja vibracijama za posmatrani mod oscilovanja se može povećati promenom koeficijenata PID regulatora, ali u isto vreme moguće je narušiti stabilnost sistema. Nestabilnost sistema je najčešće uslovljena pojavom 'spillover' efekta. U ovom radu predstavljen je značaj 'spillover' efekta u zatvorenim petljama piezoelektričnih aktivnih struktura, kao i značaj promene koeficijenata PID regulatora na stabilnost sistema. Eksperimentalni rezultati sistema aktivnog prigušenja vibracija su predstavljeni u radu i daju jednu od mogućnosti za povećanje stabilnosti upravljanih struktura.sr
dc.description.abstractPiezoelectric actuators are widely used in structural systems for active vibration control with the aim to enhance the performance of systems. The developed system of active vibration control consists of active structure, controller and high voltage amplifier. In this paper, the composite beam is host structure for sensor platform (strain gages) and actuator platform (dual layer PZT piezoelectric actuator). In order to improve the dynamic characteristics of active system, the coefficients of PID controller are changed. The effectiveness of active vibration control system at mode of interest can be improved with change of PID coefficients, but the stability of system can be reduced. The instability of the active structure is often perturbed by spillover effect. In this paper the importance of considering spillover effects in closed loop of piezoelectric active structures is demonstrated and shown the importance of change the PID coefficients in stability of active vibration control system. Experimental results which correspond to the developed active vibration control system are presented and affirmed stability on proposed active structure.en
