Aiming at the inverse piezoelectric effect of piezoelectric ceramics
a piezoelectric-driven precision flow valve has been used as actuator
a model is built based on mathematical relationship among the driving power
the output displacement and the output flow.In view of the non-linearity
hysteresis
creep and other properties of piezoelectric ceramics which affect the control precision and control is complex.A proportional fuzzy control method is proposed and obtained more ideal results compared with commonly used control methods.
