| Abstract: | The paper design a optimal control system for cylindrical heating furnace with the outlet temperature as principal control parameter and gas flow capacity as supplementary control parameter. The cascade control loop is used in the system to make the stability of outlet temperature. To get the maximum thermal efficiency of the system, control algorithm adopts the combination of routine control and online self-searching optimal control. The main control processes in the system are thermal equilibrium control of gas flow and optimal control of excess air coefficient. The designed system has been used in practice, the control results show that the scheme is feasible, stable, and able to constrain interference. |
