In this paper, a novel mathematical piezoelectric hysteresis model based on polynomial is proposed. This model uses quadratic polynomial and linear equation to describe the relationship between input voltage and output displacement precisely. To describe the hysteresis characteristics, experiments are performed with three kinds of input triangular wave signals. The simulation results are compared with the experiment data to demonstrate the validity of this proposed model. The results show that the mathematical model can completely match the hysteresis of the piezoelectric actuator at lower errors.
