摘　　要：针对压电陶瓷微位移器的非线性问题进行了深入的研究，提出了使用该方法可以将压电陶瓷微位器的非线性度从２５％降到４％，这是一种简单、方便、可靠、成本低的非线性补偿方法．文中对压电陶瓷微位移器的非线性机理做了深入的研究，并给出了一个基于ＩＢＭ４８６计算机与ＭＣＳ９８单片机以及测试试验台组成的一个完整的试验系统．Some problems such as non-linearity of piezodectric ceramic actuator have been studied in this paper.The method of software correction has been designed to compensate the non-linearity.And the non-linearty is reduced from 25% to 4%,this is a simple,reliable and low cost method.The reason of the non-lineatity of piezodectric ceramic Actuator is studied too,and an experiment system including IBM486 computer,MCS98 single Chip computer and measuring equipment is demnonstrated in this paper.
