Linear Drive of Non-Linear Piezoelectric Actuators.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1994 Piezoelectric ceramics are ferroelectric, and are fundamentally nonlinear in their response to the applied voltage signal, showing a significant hysteretic loop. This paper deals with the linear drive of nonlinear piezoelectric ceramic actuators. It is shown that the expansion of a ceramic actuator can be approximated by a third-order polynomial in the
