摘要
冷水阀门一阶惯性控制偏差项造成洁净空调温湿度控制效果较差.为此,提出洁净空调冷水阀门一阶惯性滞后PID独立控制方法.该方法在考虑室内环境基本信息的条件下,建立环境与冷水阀的一阶惯性滞后模型;计算室内洁净空调温湿度新风量,将其作为洁净空调冷水阀门的温湿度独立控制的约束;利用自适应免疫遗传算法优化PID控制器参数,以此为依据实现洁净空调冷水阀门温湿度的独立控制.实验结果表明,该方法控制效果较好、节能率较高.
Abstract
The first order inertial control deviation item of the cold water valve causes the poor control effect of headroom temperature regulation and humidity.Therefore,a first-order inertia lag PID independ-ent control method for chilled water valve of clean air conditioner is proposed.In this method,the first or-der inertia lag model of the environment and the cold water valve is established considering the basic infor-mation of the indoor environment;the fresh air volume of indoor clean air conditioning temperature and hu-midity is calculated as the constraint of independent control of temperature and humidity of the cooling wa-ter valve of clean air conditioning;the adaptive immune genetic algorithm is used to optimize the parame-ters of PID controller,based on which the independent control of the temperature and humidity of the cool-ing water valve of the clean air-conditioning is realized.The experimental results show that the method is effective and energy-saving.
