According the feature of mine local ventilator, the paper proposes a kind of control method combining fuzzy neural network (FNN), genetic algorithm (GA) and PID control to local fan. The GA is used to optimize central value and width of the FNN's membership function, and the BP algorithm is used to optimize the connection coefficients. The experiment shows that the system can adjust automatically fan's speed according to variation of gas concentration. Compared with conventional PID controllers, this method has obvious advantages. The design of PID controller and speed control of frequency converter can be made with TMS320F2407 DSP system.
