摘要
除湿箱是给船用电子机柜提供温度、湿度符合要求的循环空气,而温湿度控制系统是时变的、非线性的、具有纯滞后的大惯性系统,控制效果与控制算法密不可分,传统的PID控制算法中,存在建模困难和超调量大等问题,针对这一情况,在除湿箱的温湿度控制研究中,采用了一种模糊控制算法实现了对循环空气的温湿度控制,试验结果表明,该算法的控制效果较好。
A temperature and humidity controller using fuzzy algorithm for chiller is studied in this paper. The practical operation has shown that this control algorithm can achieve quite good control performance.Furthermore, this kind of controller is much more robust than conventional PID controller when applied to the nonlinear, the large time delay, time—variation and coupling plants.
