The object of this research is to prototype a hybrid driving circuit (AC+DC) for nano-manipulation mechanisms employing piezoelectric actuators. The experimented analog driver is triggered by digital signals and commanded by a PC which is loaded with a graphic user interface code (GUI). The developed hybrid circuit can therefore precisely drive the piezoelectric actuators as to fulfill high resolution...
The object of this research is to prototype a precision system, which mainly consists of a piezoelectrically actuated cantilever beam structure as powered by an AC + DC hybrid driving circuit. Pulse width modulation (PWM) control algorithm as well as nonlinear tabulation are developed to capture characteristics of the specific hybrid driver and actuator, while dedicated driving techniques are elaborately...
