锅炉过热汽温的预测智能控制

针对锅炉大迟延，大惯性特性，提出一种新型控制方法。该方法首先由预测器预测出未来过程输出，然后根据偏差状况及预测输出变化趋势通过模仿人的控制思维方式来选择相应控制强度，在过热汽温控制系统应用仿真结果表明：其控制品质地常规控制规律，并具有较强鲁棒性。

The Prediction and Intelligent Control of a Boiler Superheated Steam Temperature

In the light of a great hysteresis and inertia specific to boilers presented in this paper is a new type of control method. Under this method a future process output is first predicted. Then, on the basis of existing deviations and predicted output change trends a corresponding control intensity can be selected by simulating the human control thought. When used on a superheated steam temperature control system the simulation results show that the control quality achieved is superior to that of a conventional control method. Furthermore, it also features a relatively high robustness.
