  Aiming at the tube mill burthen controlled object with the characteristics of large delay,large inertia,nonlinear and time-variant,we design a tube mill burthen control system basing at fuzzy immune PID control.The system combines the cascade control with the fuzzy immune PID control,and adopts P control in the inner loop and fuzzy immune PID control in the outer loop,taking fully advantage of the cascade control,fuzzy control,immune feedback control and PID control,which makes the system have not only better track ability but also stronger robust and anti-disturbance.In order to show the supe-rior of the control strategy,simultaneously the paper carries out cascade PID control Simulation,and the result manifests that the control effect has better regulation-quality than cascade PID control,in some sense equaling with the internal model con-trol and Smith predictive control.But because of consisting the immune fuzzy control,its non-linear control effect is better than internal model control,Smith predictive control,PID control Cascade.What s more,the control algorithm is very simple and practical.……
