本文介绍了应用微型机控制温湿度试验箱的一种控制方法。它用计算机和很短的程序就达到了理想的效果。采用的方式是一种带有逻辑判断功能的非线性超前控制。其控制精度和波动度远远优于 PID 控制,成本、能源消耗也有较大幅度的下降。 This paper introduces a control method of microcomputer control temperature and humidity chamber. It uses the computer and a short program to achieve the desired effect. The method used is a non-linear advanced control with logic judgment. Its control accuracy and volatility is far superior to PID control, cost, energy consumption also have a more substantial decline.
