A solution is proposed for the synthesis of optimal control.
Conceptual solution for the synthesis of optimal control
Two levels of control are proposed: maintaining a constant height of the empty pile and increasing the temperature of the cast iron by controlling the air supply to the tuyere box
Construction of the optimal law for regulating the level of the height of the empty charge
It is shown that the problem of regulating the upper level of the empty charge can be solved using the Pontryagin’s maximum principle.
Visualization of the temperature profile of cupola along horizons:
1 – empty charge;
2 – metal charge;
3 – coke charge
Synthesis of optimal control of air supply
The synthesis includes 7 consecutive stages, based on experimental and industrial studies, which precede the search for optimal control.
Control of the temperature profile of the cupola
The use of D-optimal plans for the selection of sensor installation points allows determining the temperature profile of the cupola with maximum accuracy.
