PID control
Thread Content
With the Yokogawa CS300, during actual tuning, some nodes respond very slowly, and PID adjustments show almost no effect. What is the reason?
No way, I guess there’s an issue with your PID parameter settings.
A specific analysis is needed: first, what are the values of the PID parameters?； II. Is there a trend in PV, SV, and MV? It would be good to show some perturbations to observe the changes in the trend graphs
