摘要：超声波雾化技术由于其良好的雾化效果获得了广泛关注，具有极大的研究价值和应用前景。但是在超

Abstract: At present, ultrasonic atomization technology has received extensive attention because of its good
atomization effect, which has great research value and application prospects. However, in the process of
ultrasonic atomization, due to the temperature change, stiffness change of the transducer, load change in water
and other factors, the phenomenon of resonant frequency drift will occur. Once the working frequency is not at
the resonant frequency point, it will reduce the working efficiency of the transducer and damage the electronic
components. To solve this problem, a frequency tracking algorithm of ultrasonic atomization power supply
based on improved particle swarm optimization algorithm to optimize PID parameters is designed. Simulation
and experimental comparison of the algorithm for frequency tracking have been conducted, achieving better
results in frequency tracking, enabling the transducer to work stably in resonant state, and improving the
utilization rate of power supply.
