Fuzzy PID Other relevant mathematical foundations , For theoretical knowledge, you can refer to other articles in the column , No more details here , In this paper, the fuzzy of double tank PID Explain the problem in detail ( Including all source code and fuzzy rule setting parameters ). Limited to my ability , Mistakes and deficiencies are inevitable in the text , Sincerely welcome your criticism and correction , At the same time, thank you for your attention and subscription .

PLC Fuzzy control learning notes _RXXW_Dor The blog of -CSDN Blog _plc fuzzy control 1、 Some fuzzy control systems require that the fuzzy universe E and EC Normalized to a certain range 【a,b】 Between , This can be achieved by scaling , Portal PLC There are many ways to do this , See an article I wrote , About analog conversion ：PLC Analog output Analog quantity conversion FC S_RTI_RXXW_BOSS The blog of -CSDN Blog _plc Analog output 1、 This paper mainly shows several methods of Siemens botu analog output conversion , Method 1： First show me the self-made FC: The calculation formula is as follows ：intput intput Real ISH Real // Upper limit of quantities ISL Real // Lower limit of quantities OSH Int // Upper limit of digital quantity OShttps://blog.csdn.net/m0_46143730/article/details/124380674

For fuzzy quantization factors and scaling factors, please refer to the following blog post , I have a vague understanding of everyone PID It will help
