摘要
针对火电厂变负荷机组汽温系统动态特性的时变大迟延特点 ,首先给出了广义预测控制律的简化算法 ,在此基础上提出多模型广义预测控制方案。分析了多固定模型的选取问题 ,给出了在特定工况下的模型选择依据。仿真结果证实了算法的有效性。
In view of the features of main steam temperature system with large time delay and fast time varying in a power plant,the paper presents the simplified GPC algorithm and puts forward a multiple model GPC conception.The determination of multiple fixed models is analyzed and the method to select models under a special condition is given.The computer simulation results show the effectiveness of this method.
