Abstract

In order to improve the response speed, adjustment accuracy and anti-interference performance of the outlet temperature of the heat exchanger of the thermal performance test bench. An algorithm combining fuzzy control, Smith prediction and traditional PID control is proposed, and use Matlab/Simulink to simulate the temperature characteristics and Anti interference characteristics of the system. The experimental results show that compared with the traditional PID and Fuzzy PID algorithms, the response speed of Smith fuzzy PID is 57S and 50S faster 8 than that of traditional PID and Smith PID, respectively, and the overshoot is 18% and 16% less than that of traditional PID and Fuzzy PID respectively. Combined with Smith prediction algorithm, the time lag problem is effectively solved. Therefore, the Smith fuzzy PID control method has a faster response to the outlet temperature control of the heat exchanger, a smaller overshoot, and a faster response to interference signals.
