摘　　要：文章概述了在功率超声中自动频率跟踪的基本原理,在分析自寻最优控制方法和模糊控制方法的基础上,提出一种自寻最优模糊控制方法,利用它来实现自动频率跟踪,在超声吸引器上取得良好的应用效果。The principle of automatic frequency tracking for the power ultrasonic vibration system is summarized. A self-optimizing fuzzy control approach is presented through the analysis of the self-optimizing control approach together with the fuzzy control method. The function of automatic frequency tracking is implemented. Experiment with an ultrasonic aspirator is carried out with a desired result.
