英文摘要：
The hybrid system is used to analyze the hybrid properties of the heating process in coke oven. A hybrid hierarchical control structure for heating process in coke oven is proposed, which includes a decision-making layer, an intelligent temperature control layer and a process control layer. The heating process of coke oven is synthetically analyzed, the process states are classified with expert reasoning and statistical methods according to＇the temperature of raw gas, and the temperature controllers are accordingly decided. According to this decision-making information, fuzzy control rules are built with weighted parameters, and intelligent temperature controllers are designed for coke ovens with complex processes. Results from practical operation prove the effectiveness of the presented control method.
