一种超声波加湿结合人工遗传算法的加湿系统

Humidification System Combining Ultrasonic Humidification Combined with Artificial Genetic Algorithm

介绍了一种采用超声波雾化原理对目前温湿度控制需求的老化箱的一种优化后的加湿算法。首先,采用超声波加湿比原有通过加热加湿的方式优点在于不带有水汽温度的引入,从而不会造成控制系统中出现额外的温度变量引起的控制波动和失效;其次,采用新型GA-PID遗传算法进行湿度控制,可以有效降低温度条件对温度条件耦合的影响,极大程度保证控制精确度,降低波动,防止超调。

This paper introduces an optimized humidification algorithm for the aging chamber that uses the ultrasonic atomization principle to control the current temperature and humidity requirements.The advantage of using ultrasonic humidification firstly by heating and humidifying is that there is no introduction of water vapor temperature,so that control fluctuations and failures caused by additional temperature variables in the control system are not caused.Secondly,a new GA-PID genetic algorithm is adopted.Humidity control can effectively reduce the influence of temperature conditions on temperature condition coupling,greatly ensure control accuracy,reduce fluctuations,and prevent overshoot.
