The application of fuzzy-PID in control system of THJ-2 temperature experimental device

The object of temperature control in THJ-2 experimental device has the characteristics of long delay and large inertia Due to the traditional PID control algorithm can not has satisfied performance on temperature control, a Fuzzy-PID control algorithm was introduced to apply in the system. Based on the object of temperature control the THJ-2 temperature device, a mathematic model was establish and simulated by Matlab, and the Fuzzy-PID algorithm was used to control the temperature. The simulation results show that the Fuzzy-PID control algorithm has shorter response time than traditional PID algorithm, it also can decrease the overshooting and improve the robustness of the system efficiently.
