All-pass filter for active vibration control on a cantilever beam

Popis výsledku v původním jazyce

This paper shows how the all-pass filter can be implemented into a control algorithm for active vibration control on a cantilever beam. The laboratory structure of the beam is designed as a non-collocated pair of sensor and actuator, while the stack piezo-actuator is used to suppress vibration. The algorithm uses a second order all-pass filter. The amplitude of this filter is unity, but the phase shifts the signal from zero to -360 degrees. This ability is used to change the polarity of the actuating signal with respect to the characteristics of the plant. The results show that said filter could be successfully used to reduce the first three vibrating modes of the single-clamped beam. This experimentally oriented paper presents a short introduction of the laboratory equipment, along with identification and simulation processes and the subsequent presentation of the results.
