piezoelectric actuator linear drive hysteresis electric leakage displacement drift temperature behavior
Piezoelectric ceramic is ferroelectric and is showing a significant hysteretic loop in its displacement response. This paper deals with the development of a linear compensation circuit for piezoelectric ceramic actuators by the self-sensing feedback control technique. In this paper, the concept of self-sensing feedback control technique and the circuit design were presented in detail, and the effect of the electric leakage in the piezoelectric actuator was investigated. A new idea for improvement of the effect of the electric leakage on the displacement drift in piezoactuator has been proposed simply by adding compensatory resistors in the circuit.
