Study on Fuzzy Control System of Setting and Separating of Red Mud

Abstract:

Good settling properties of red mud are one of what contribute to smooth production of alumina. Many manufactories still adopt manual control on taking quantitative flocculants to control clarity of clear solution. This paper mainly studies a Genetic Algorithm-based adaptive fuzzy control device based on fuzzy control and genetic algorithm, and also focus on analyzing adaptive fuzzy control of clarity of clear solution, through the test of overflow, baseflow and a flocculants addition as adjustment method. From the results of control, the system can get a better control response, which satisfies the requirements of practice works, compared with ordinary PID control.
