Optimization of PID parameters for coal gas monitored control system based on aritificial immune algorithm

Based on immune algorithm a novel optimization design scheme of PID speed controller parameters is proposed for the coal mine gas monitored control system in this paper. The principle of Immune algorithm is introduced, and the strategy of PID controller parameters based immune algorithm is discussed. According to the response between antigen and antibody, the PID controller parameters are optimized in order to make the local fan adjusted quickly and stably. The simulation show that immune algorithm PID controller has a faster response time and smaller overshoot compared with the traditional tuning method. It not only improved the adjusting time of local fan, but also achieved energy saving and wind saving. The strong robustness and high tracking performance of the control system applies to the coal mine environment.
