超临界直流锅炉对象特性及控制策略的研究

Study on supercritical once-through boiler characteristics and control strategy

介绍了超临界直流炉的控制特点,分析了其控制系统的现状及难点。针对超临界直流锅炉多变量、非线性、大迟延、大惯性的特点,提出了合适的控制策略,在理论上进行了比较深入的分析,为超临界直流锅炉控制策略的选择提供了参考。

The article describes the controlling characteristics of supercritical once -through boiler, and analyzes the existing status and difficulties in their control systems. This boiler features multivariable, nonlinear, big inertia and large time delay. Some appropriate strategies are proposed, which gives further analysis in theory and provides a reference for the controlling strategy＇s choices.
