Advanced Control In Hazardous Waste Burning Dispose System

With the rapid development of control theory and modern industry, more and more advanced control technology has been applied to industry process control. In the field of process control, the major problems are process modeling and advanced control. This thesis, which is based on the project "The system of hazardous waste burning disposal", discusses the technologies of process modeling and advanced control theory.The main contents of this thesis are following:1. The basic theory and develop status about process control, process modeling and advanced control have been introduced. The background, key and crafts of hazardous waste burning disposal have been introduced, too.2. On the based of field real-time data, the two key parts, burner to temperature, blower and draught-fanner to oxygen content and inner negative pressure, have been built model by the method of system identification.3. The basic design of fuzzy controller has been introduced and a fuzzy controller is designed and applied in waste gas disposal system. The effect is good.4. Because of non-linear problems in hazardous waste burning disposal, we designed a emulation instance using ANFIS method, and it's result is good. With applying AINFS in hazardous waste burning disposal, we designed a burner temperature controller and a draught-fanner to oxygen content and inner negative pressure controller, and put into practical applications. Compared with normal controller, systematic function improves notably.5. The design and implement of the control system of hazardous waste burning disposal are introduced. The system works well, since it began to use.
