| Abstract: | On the basis of the technology regime of the car-type annealing furnace, the L1 and L2 control systems are developed. The incremental PID arithmetic is used in the L1 control system, and the ternary model considered the thermocouple is used for key model in the L2 control model. The heat processes for each stage are simulated by the model, and the temperature fields for the ternary heat sources are solved. Meanwhile, the time from warming stage to heat preservation stage is considered by the model, and the stability for the control system is obtained in the transient process. |
