摘　　要：针对热轧层流冷却过程具有强非线性、分布参数和时变等综合复杂特性,提出了基于案例推理技术的层流冷却过程喷水系统的智能设定方法.层流冷却过程的典型工况及喷水系统设定值以案例的形式存于案例库,对于待冷却的带钢,根据当前的工况描述特征在案例库中检索匹配的历史案例,经推理完成当前工况下喷水控制系统的设定.采用某钢铁公司热轧层流冷却生产过程的实际数据进行仿真实验,结果表明所提出的智能设定方法在工况变化时是有效的.An intelligent method is developed for setup of the spray system in the laminar cooling process, which is very complex in nature (e. g. highly nonlinear, time and spatially varying). Typical cases in the process control history including operating conditions and number of active cooling units are stored in the case base. The number of active cooling units for the current operating condition is found using case-based reasoning. Experimental studies with industrial data from a steel plant show the effectiveness of the method in case of varying operating conditions.
