Research on brine flux control based on fuzzy-immune PID algorithm in freezing station

According to the characteristics of pure delay, time-varying and nonlinear in brine freezing sinking flow control system, therefore, the author imported the fuzzy theory into intelligent immune feedback control algorithm and designed a kind of embedded intelligent flux controller based on fuzzy-immune adaptive PID algorithm. Results show that this controller has better static and dynamic control performance than traditional PID control and fuzzy PID control, what´s more its overshoot is less, adapt ability is better, stable speed is faster, which has good significance to technology renovation of frequency control of coal mine freezing sinking.
