摘要
压电／电致伸缩陶瓷作为一种理想的微位移器在许多领域得到了广泛应用，但是由于其存在迟滞、蠕变及非线性等不足，限制了它的进一步应用．本文在分析压电／电致伸缩陶瓷极化机理的基础上，给出了压电／电致伸缩陶瓷归一化的控制模型，同时给出几种情况下的典型例子及其电压同位移的关系曲线。
As ideal micro-displacement actuators, piezoelectric and electrostrictive elements have been widely applied in many fields. But its further application is restricted because of its drawbacks such as hysteresis, creep and non linearity. From the analysis of polarization mechanism of piezoelectric and electrostrictive elements, a new normalization model was proposed. And typical examples and displacement voltage curves are given under several conditions are too. Moreover, it is proved that hysteresis can be reduced by using polarization intensity control method.
