The frequency tracking of the ultrasonic atomization power supply based on improved particle swarm optimization
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.
