FB80 Lead lag filter

Hi
What unit is the Sample_T input suposed to be in? In the instance DB it sayes that the Lead and Lag times are to be given in minutes as a Real number; is the samle_t suposed to be in miliseconds or the same unit as the Lead and lag, i.e minutes?

It makes no difference which time units you use.

You must be consistent. You determine the unit by the setting the sample time. The units should be the same as the sample time units.

A lead lag filter may be used for closed loop control. Lead/lag filters work well in some cases. The problems is that few have any idea of how to tune a lead/lag filter.

Thanks for my chemistry projects so easy, after studying your lead lag filter theory, I am able to solve some of my chemistry question which were out of my quest. Please give me some lead in the organic pressurize unit too.
