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.
