piezoelectric actuator linear drive reduction of hysteresis nonlinear preamplifier
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 applied voltage. A linear drive method is proposed for the ceramic actuators that compensates for the hysteretic loop, and then a simple nonlinear preamplifier is developed based on the drive method proposed. An experiment is conducted to verify the effectiveness of the amplifier. It is shown that the hysteretic loop disappears when the nonlinear preamplifier is installed between the d. c. amplifier and the input voltage generator.
