Abstract:

To enhance the freezing quality and decrease the energy consumption of freezing sinking efficiently,the authors design a kind of control system which is composed of an embedded system and an expertfuzzy adaptive PID flux controller,and what’s more,this system integrates the virtues of high efficiency, realtime control performance and  rapidity,as well as the accuracy and stability of the expertfuzzy adaptive controller, thus it proposes a good resolution of intelligent flow control for coal mine freezing sinking .The experimental results show that,in the control process of freezing sinking brine flow control, applying the embedded hybrid controller can obviously get better adaptability,less overshoots and a more rapid rate of stabilization than the single expert PID or the fuzzy PID controller, and it will bring a good economic prospect.
