为改进目前火电机组机炉协调系统预测控制的效果,在多模型子空间预测控制研究的基础上,利用子空间方法直接从数据中得到预测控制器,并将数据驱动子空间预测控制与基于子空间的多模型预测控制两种控制策略进行仿真比较,结果表明所研究的控制方法可行且有效,为进一步研究提供了思路。
To improve the predictive control effect of current boiler-turbine coordinated system in coal- fired power unit, on the basis of predictive control research for multi-model subspace, the subspace method was used to obtain data directly from predictive controller. Simulation results of both the data-driven subspace predictive control and subspace-based multi-model predictive control were compared. Results show that the method proposed is feasible and effective, which may serve as a reference for further research of similar problems.
