多模型过热汽温控制系统

Multi-model Control System of the Boiler Superheated Steam Temperature

提出了多模型双回路超临界 ６００ ＭＷ直流锅炉过热汽温控制方法。该方案在采用导前信号的双回路控制系统的基础上，选择合适的多模型特征参数，划分合理的工作子空间，建立模态调度规则，实现准确的模态切换。仿真结果表明，用这种方法建立的过热汽温控制系统，具有较好的控制品质和较强的自适应能力。

Based on the two-loop control system with derivative signal, a new multi-model superheaded steam temperature control system of a supercritical once-through 600 MW boiler is presented. In the new scheme, the multi-model feature parameters are chosen appropriately, the working space is separated, the multi-model switching principle is built, and the multi-model switch is implemented finally. The simulation results show that this control system has better performance and stronger adaptive ability.
