| Abstract: | This study chose a new Siemens S7-1200 SIMATIC PLC as the core controller,based on a self-designed experimental platform,used fuzzy PID control strategy,calculated the control scale in the offline condition in MATLAB,got and online changed the parameters of PID controller by the way of addressing and online look-up table,to achieve control of the electric heater.By using the configuration software of S7-1200 and online monitoring,the pictures of the control effect were got.The experimental results proved that,fuzzy PID control was fully realized through S7-1200 and an excellent control effect was got.So the study can be well applied to the industrial engineering. |
