| Abstract:pH value is a nonlinear object with large time delay and strong interference in the anaerobic process of papermaking wastewater. Therefore, this paper designed the pH cascade control system based on expert adjustment of fuzzy PID quantization factor. The system used the expert rules to adjust quantization factor of fuzzy control, so as to improve the accuracy of fuzzy controller. Application results showed that the control system possessed edvident practicality and load efficient control result. |
