PID tuning for DCS control system
Thread Content
Newcomers to the DCS role can take a look to gain a deeper understanding of DCS operations.
I just took a look; in example 3 of version 4.3.1, based on the waveform diagram, the peak value should increase correspondingly with the trough value. However, in your analysis it is stated that there is no phase difference – could this be a typo? Because what you said – that an increase in the P-value means increased control – contradicts your claim that an increase in the P-value leads to decreased control; therefore, I doubt that you might have made a typo in your analysis. . .
Download it and take a look; it’s easier to understand how to adjust it if there are trend charts
