摘要

压电材料作为传感器和致动器被广泛应用于许多领域。它们允许对机械系统进行有效的数字控制,但存在非线性和滞后。本文提出了一种适用于家用电器实时控制的新型压电弯曲器数字开环控制方法,该方法要求高、精度好、成本低。该控制算法在单片机中实现,解决了非线性和滞后的问题。本文介绍了在Indesit公司实验室实现的样机的实验结果,以供将来在家用电器上的应用。

Digital control of low-cost piezoelectric actuators for household appliances
Piezoelectric materials are widely used as sensors and actuators in many applications. They allow efficient digital control of mechanical systems, but suffer from nonlinearity and hysteresis. This paper presents a new digital open-loop control of piezoelectric bender for real-time applications in domestic appliances, for which strong specifications are good accuracy and low cost. The control algorithm, implemented in a microcontroller, solves the problems of nonlinearity and hysteresis. The paper presents experimental results of the prototype that has been realized in the Indesit Company laboratories for future applications on domestic appliances.
