Hello, gentlemen! I apologize for any possible repeating the theme or perhaps a trivial and obvious question, but I do not know where it has to find the answer ... At the moment, I want to configure the PID controller for PLC Siemens, knowing the PID controller in Matlab / simulink. Could, please, answer the question of coefficients PID: integration time and differentiation in STEP7? In STEP7, in FB41 CONT_C box "integration time" referred to as TIME: = T # 20S; and "derivative time" - TIME: = T # 10S; With this kind of PID controller in Matlab / simulink (right): Please tell me how I need to write coefficients for I and D in STEP7? P (GAIN) - is clear everything is just the value of 3,618 (and that's -? "TI" (1 / 0.0096) and D "TD" did not understand a little bit ... The manual for the PID block in STEP7 read, but did not understand the implementation .. I know that the formula for PID SIEMENS looks that way, but then again it is not clear how it will look for an analogy with the PID Matlab: Page with the formula for the PID: 4-46 https://cache.industry.siemens.com/dl/files/084/1137084/att_27128/v1/Standart_PID_ru.pdf Thanks for the answer! Best regards! |
