Hola Greg, how important is to determine the lag caused by my measurement system?

At a bump test I will note the associated delay time and the change in my process variable; any lag in my measurement will be already be acting over the observed dynamics. Since the computed tuning parameters will be based on these, they will be already acounting for such measurement lag; will it make a difference determining how much is coming from such source?

When will it be important to determine the measurement lag?

Gracias;

Héctor
