The paper mainly researched the applications of predictive functional control (PFC). Predictive control is a new type of control algorithms, PID control method is simple and convenient,but accuracy is not exact. In recent years, the adaptive, self-tuning method is high accuracy, but , all of them require object model identification on line, but the adaptability of the unmodeled process dynamics and disturbances is poor , robustness bad.. Predictive control method is the third generation of model predictive control algorithms, with the characteristic of model low, small real-time control calculation, precision tracking control, is an industrial process-oriented algorithm.Firstly, the paper research the basic principles and characteristics of the predictive functional control algorithm ,Conclude essence of the realization of advanced control from the four characteristics of predictive functional control, and used predictive control algorithm to the large time delay objects , Conclude the advantages of predictive control of large time delay object by comparing with the traditional PID control.Secondly, the paper designed predictive control to apply to industry. Also the control tool KingView commonly used in industry, that has little capability of calculation , and in the predictive functional control, the calculation is very large , programmed complex, so,if programming on KingView only, it is difficult, so, used MATLAB to calculate and program, MATLAB and KingView data exchange between the dynamic data exchange technology (DDE).Finally, used PCI-â…¢process control system devices as a platform, put the predictive functional control algorithm with the temperature system. The experimental results validate the advantages of predictive control with control large time delay object, has a reliable and practical application of practical value about predictive control for the industry .The paper mainly made up with predictive functional control theory, predictive controller design and experimental, which studies predictive control theory and method and how to connect the KingView and MATLAB,brings the advanced theory into practice. The experiment is very successful,which shows that Predictive Control method is really excellent in industry control.
