At the moment, there is a need for the implementation of fuzzy logic (fuzzy controller) for S7-300, writing specifically for cfc,ST, ladder - does not really matter. The essence of the project is to create a fuzzy PID controller under STEP7, object of regulation in Matlab / simulink. The problem itself is to write fuzzy controller using Step7. I want use Matlab ->OPC->STEP7(FuzzyPID)->OPC->SCADA. but due to lack of knowledge can not apply this LAD or ST algorithm.
I have a model in Matlab, with disturbance and PID control, I want to check out how to work the fuzzy regulator PID for a place on the s7-300 (or PLCSIM).
As a result of the work, you need to implement only a fuzzy controller Step7 (for s7-300) on the basis of rules and membership functions set for the model from the Matlab / simulink.
