Application of Fuzzy PID Control Based on GA in Control Valve

Abstract:

In order to improve the dynamic characteristic of regulating valve system based on traditional fuzzy PID, a control strategy was presented and this method combines fuzzy PID and improved GA (genetic algorithm) to optimize fuzzy rules. Finally a simulation was carried on in MATLAB. The results show that: Compared with the traditional PID, the fuzzy PID enables the system to achieve better dynamic characteristics.
