Application of Genetic Tuning Based Fuzzy Immune PID Controller in Liquid-level Control System

With the combination of genetic algorithm, fuzzy control and immune feedback mechanism with the conventional PID control, a fuzzy immune PID control algorithm based on genetic tuning is proposed. The algorithm is applied to the experiment of two container liquid level system. The results show that the algorithm is better than the conventional PID control. It has practical application value in industrial production process.
