To use traditional air - conditioner to control temperature , a precise mathematical model is essential to pid algorithms . while in fact it is difficult to do it 而且传统空调采用pid控制算法,需要建立被控对象的精确数学模型,也不易获得。
The co2 gases trap the heat of the sun in the same way the glass of a greenhouse controls temperature for plants 我的译义:二氧化碳气体也同样吸收太阳的热量,对于受温室效应使气候变化,树木像一个晴雨表。 (我也不知对不对,请老大们多多指教。 )
It is generally well known that controlling temperature accurately and with fast process response times presents practical difficulties to standard programmable logic controllers 众所周知准确地控制温度和与快速的处理实际的问题使用标准可编程序逻辑控制器。
