The Application of the Fuzzy-PID in the Circulating Water Control System with Constant Pressure

Article Preview

Abstract:

By analyzing the characteristics of the circulating water control system with constant pressure, we established the mathematical model of the system. However, the system with conventional Proportional-Integral-Differential (PID) controller can not achieve excellent dynamic and static performance. An adaptive Fuzzy-PID controller was designed by combining Fuzzy and PID control methods. And we simulated the system in MATLAB/Simulink with the methods of conventional PID and Fuzzy PID respectively. Compared with the method of conventional PID, the results showed that the method we had proposed has the better effect than conventional PID
