Derivative kick in pid controller
John Ziegler and Nathaniel Nichols, the fathers of PID loop tuning, recognized as far back as 1942 that derivative action dampens the control effort. They discovered through trial and error that setting the derivative time to at least half of the process deadtime would slow the controlled response to a step change in … See more If you think in terms of what the controller wants to do in a given situation, you can begin to analyze how the factors are working at any point in the process. Looking at the … See more This all sounds very positive, so where does the problem come in? Buckbee compares using derivative to learning to drive: “Derivative is like trying to drive your car with one foot on the gas and one foot on the brake. To my … See more So if the main purpose is slowing the control effort of the other factors, what’s D good for? Fast acting loops, such as flow and pressure loops, don’t really need it. If a loop can change in a matter of seconds or a minute or two, … See more Even in situations where loops move slowly and fit the description for appropriate derivative deployment, you have to be careful how much you use. Rice suggests that if … See more WebIn general, PID structures should have derivative action on the process variable and not error unless the resulting kick in the PID output upon a setpoint change is useful to get to setpoint faster particularly if there is …
