【摘要】 本文介绍一种基于动态平衡思想实现的对空气温、湿度两个变量进行高精度控制的系统设计方法，该方法克服了空气参数的滞后问题，并且采用微机对两个变量间的耦合关系进行予估补偿，而不必为实现解耦去测试对象的数学模型．辅以微机实现的Ｂ－Ｂ控制及变速积分ＰＩＤ控制，从而以较低的成本获得了比较满意的温、湿度控制效果．更多还原

【Abstract】 This article introduces a kind of system design method of controlling air temperature and humidity in high precision. It is hased on the thought of enthalpy dynamicbalance. This method overcomes the delay of air parameter, and it u$es computer to predict and offset the coupling relationship between the two variables, so it neednlt the targetmathematic model; it takes use of B-B control and variable speed integeration PID control, so the whole system achieves a satisfied control effect with low cost.更多还原
