Disturbance Location and Speed and Process Delay/Lag Ratio

Last week we discussed the effect of disturbance timing on performance. This week we turn our attention to the location and speed of the upset and the Delay/Lag (dead time to time constant) ratio of the process. Most control text books and papers show a step disturbance on the process output, which is the process …
