带死区的增量式PID控制在湿度控制中的应用

Applications of the increment PID with dead-band in humidity control

湿度的自动控制无论是在日常生活还是在工农业生产中都得到了广泛的应用,利用微机对湿度进行测控的技术得到日益发展和完善,越来越显示出其优越性。文章密切结合某高校实验室环境湿度监控的需求,研究与设计了一种带死区的增量式PID控制算法,其中采用的可靠性设计方法和低成本实现技术具有一定的推广应用前景。

In no matter what daily life or agriculture and industry, automatical control for hunmidity has been widely applied. The microcomputer to measure and control the humidity has developed daily and perfect, and increasingly demonstrated its superiority. This paper nearly follows the demands of the humidity in some university laboratories , a increment PID with dead-band control algorithm is adopted to control the humidity, because of its brief structure, low price, convenient maintenance, the system can be widely applied in the situation which has the strict request for the humidity.
