電廠的主汽溫是大慣性、大滯后的對象，并且動態特性隨機組負荷變化而變化，運
行過程中擾動多。本文采用模型參考自適應控制的思想，將模糊控制方法和內模控制方法結合在一起，提出了一種模型參考模糊自適應內模控制方法：采用相消法設計內模控制器，用參考模型理想輸出和實際對象輸出之差e 及其變化率△e 在線模糊調節控制器中濾波參數。本文方法綜合了模糊控制，內模控制和自適應控制的優點，增強了系統的魯棒性，針對電廠熱工過程系統的仿真研究結果證明了這一方法的有效性。

ABSTRACT：The main steam temperature transfer function of the power plant is the large inertia large delaying and more disturbances. Moreover, the dynamic changed with the load. In this paper the author propose a model reference fuzzy self-adopting IM controlling method based on the combination of the fuzzy and IM controlling theory and design the IM controller using the relative arithmetic; in order to get optimic steadiness the filter parameters can be tuned through calculate the error-e between the computation outle and the test result as well as the changing rate. The simulated result shows the method lead to the optimizing dynamic characteristic for the plant process controlling.
