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.
KEY WORDS： model reference, IMC, fuzzy controlling, steam temperature of superheater
