摘要
环境实验室温度、湿度变化具有非线性、大滞后、精度要求高、建立数学模型复杂等特点,传统控制方式具有精度不够或模型复杂等限制。根据系统需求,通过温度及湿度传感器采集数据,基于模糊控制理论,通过制定规则,选取参数因子,经过模糊控制算法运算,得到合理的控制量,通过控制量驱动控制装置,使温度、湿度趋向设定值。本设计与传统控制方式相比在收敛速度、控制精度、系统稳定性等方面具有明显的改善。
The condition lab＇s temperature and humidity have the characteristics of nonlinear, long delay,high precision and complicated mathematic model. Conventional control system has the bug of low precision and too complicated model. The data collected from temperature and humidity sensors is computed with the established rules and the selected factors based on the fuzzy control theory,the final result is acquired to control the temperature and humidity factors trend to the setting. This system has virtues of quick convergence, high precision and high stability contrast to conventional system.
