Research on Solid State Electric Heat Storage Heating Temperature Control System Based on Smith Fuzzy PID Control
The temperature control system of solid electric thermal storage heating has hysteresis,resulting in slow system response,which greatly reduces anti-interference ability and energy utilization efficiency.In order to solve this problem,based on the solid energy storage heating demonstration project of a certain university,a method based on Smith fuzzy PID control is proposed to control the temperature control system.The experimental results show that the tem-perature control accuracy of the temperature control system can reach±0.8℃,and the adjustment time is shortened by 5 minutes.The analysis results show that compared with traditional PID control methods,this control method can more effectively reduce the disturbance impact during the control process,significantly shorten the adjustment time,make the system enter a stable state faster,and effectively overcome the adverse impact of traditional large lag systems on stability.The temperature control effect is better than traditional PID control.
