| Abstract: | This paper brings forward the new method of improved predictive functional control algorithm, which is a predictive functional control （PFC） combined with PID control. It also analyzes the basic theory and characteristic of predictive functional control aiming at the typical industrial process control. Based on the Smith predictor, it presented the improved algorithm of industrial process control system, and carry out the emulational experiment by MATLAB. The emulational results show nice robustness, better ability to restrain disturbance and tracking performance. |
