动态矩阵控制在电厂热工控制系统中的应用
|
摘要
由于动态矩阵控制(DMC)能直接处理带有纯滞后的对象，对大惯性有很强的适应能力,有良好的跟踪性能和较强的鲁棒性，而主汽温对象和锅炉燃料调节对象均是具有大惯性大延迟的复杂对象，用常规PID串级控制难以取得理想的控制效果。因此，把单变量DMC和串级控制相结合，形成DMC-PID串级控制，既能保持串级控制的结构特点，又能保持预测控制的性能优点。这种控制策略用于主汽温和锅炉燃料调节系统中，取得了良好的控制效果。作为一种优化控制算法，DMC的效用更多体现在多变量系统中。多变量DMC除对惯性和延迟有很强的适应性外，还对耦合有较强的适应能力，本文把它用于单元机组负荷控制系统中，表现出强鲁棒性
Dynamic matrix control(DMC) can directly treat with objects with pure delay, has strong adaptability to large inertia, approved tracking performance and better robustness, but primary steam temperature object and boiler fuel regulating object are both intricate objects with large inertia and time delay, which are difficult to obtain perfect control effect using routine PID cascade control. Therefore, combining single-variable DMC with cascade control can form DMC-PID cascade control, which can retain structure characteristic of cascade control as well as performance virtue of predictive control. When this control strategy is applied into primary steam temperature and boiler fuel regulating systems, benign control effect can be obtained. As an optimizing control algorithm, DMC's virtue is more embodied in multi-variable systems. Multi-variable DMC algorithm has strong adaptability to coupling as well as to inertia and time delay, so it's applied into unit load control system and shows strong robustness.
