based algorithm with the correction of a forecast error has been put forward to fulfill relevant control functions. After a brief description of the DMC composition and an internal model control structure a model error is predicted based on a time sequence analysis, parameter estimation and an optimum forecast theory. Furthermore, by forecasting the model error and using the model forecast error to replace the model error the rolling optimization of a predictive control can be duly corrected. Finally, through the simulation tests of the predictive control for the boiler control system it is shown that the correction of the forecast error can result in a marked improvement in such characteristics as tracking ability, anti interference and robustness when compared with an error correction algorithm in general.
