摘要
提出了预测控制算法在监控层嵌入到DCS层组态控制软件中的应用技术。论述了该技术及其应用在某热电厂CFBB过热汽温控制中的技术方案,包括汽温对象特性描述及常规控制方案分析,改进的汽温控制方案设计。该方案将喷水减温执行机构的非线性特性的增益调度补偿、具有前馈-反馈结构的DMC预测控制和DMC-PID串级预测控制等先进控制技术综合应用,获得了良好的现场工业应用实验效果。
the development work and proposes the technique to embed the predictive control algorithm into configuration control software at the DCS level.The thesis presents the technique and its application scheme to control CFBB super-heated steam temperature in a thermal power plant.The control scheme includes that the description of controlled plant characters,conventional control scheme analysis and improved control scheme design.It integrates feed-back and feed-forward DMC with DMC-PID cascade control and nonlinear gain-scheduling compensation for actuator.Satisfactory industrial application results show that such a control scheme has enhanced robustness to the complex process,and better control performance has been obtained.
