| Abstract: |
| In this paper,the features of a phosphorus furnace are described.The characteristics of this kind of distributed parameter system such as big delay,time varying behavior,nonlinear,multi disturbance result in that it is hard to develop a practical mathematic model,and the phosphorus furnace is difficult to be controlled by only using PID control depended on precise models.In the light of present situation of phosphorus production,a new type of hierarchically intelligent control system integrating fuzzy neural network control with expert control is presented.Via simulation,a conclusion can be drawn that the system possesses is not only relative strong robustness but also superiority comparing with PID control because of its self learning and self adaptability.The system has been successfully used in operation of a phosphorus furnace of Pengyang Chemical Company.The results of the application showed the effectiveness of the proposed control system. |
