Abstract

In this paper, authors examine the design and implementation of a new charge feedback control circuitry for a voltage amplifier used in driving of a piezoelectric actuator. Actuators driven in the usual voltage feedback regime display a nonlinear voltage-displacement relationship, known as hysteresis. Use of the new charge feedback control circuitry resulted in significant reduction (70%) of the hysteresis-related nonlinearity.
