The Design and Simulation of Fuzzy PID Controller with Parameter Adjustment for Polymerizing-kettle

The algorithm characteristics for controlling of polymerizing-kettle temperature are non-linear, strong inertia,time-variant, and with pure delay. Fuzzy control and PID control are combined to design a fuzzy PID controller with parameter adjustment, to be used in the polymerizing-kettle temperature control. The MATLAB ’s simulation experiments proved that the system with the proposed controller had the properties of no overshoot , quick response, good robust. It was proved that this controller was more effective on improving the temperature’s control of polymerizing-kettle.
