Controller design for the Vector Control of Piezoelectric transducers

The Vector Control Method applied to piezoelectric transducers is a promising way to track the resonance frequency as well as to control the vibration speed. Similar to the modulation-demodulation techniques, the (d,q) transformation applied here takes advantage of the recent advances in microcontrollers. Moreover, engineers can make a bridge between the control of brushless DC motors and piezoele...
