摘要
针对压电陶瓷微位移执行器动态响应速度慢的问题进行了研究，提出用数字ＰＩＤ方法加以解决，并研制出一套实用控制系统。其中，研制出一种可微机控制的精密高压调节器，与单片机数字系统相配合，形成一个完整的、数字－模拟电路结合的控制系统，用以实现压电陶瓷微位移器动态性能的改善。实验表明，该控制系统简单、可靠、实用，所提出的ＰＩＤ方法对压电陶瓷微位移执行器的动态特性有明显的改善。
The problem of slow step response in electrostrictive actuator is studied and a digital PID method is proposed to compensate the slow step response. A microcomputer control system has been designd and made. We also design a precise high-voltage adjustor,and it cooperates well with digital hardware system and forms a inte- grated and practical control system to improve the characteristics of the electrostrictive actuator. The experiments show that the control system is a simple,reliable,and practical one,and the result of experiments is very ideal.
