Syntax
public enum PidIdentWarningFields
| Name | Description |
|---|---|
| DataSetVeryShortComparedtoTMax | The dataset needs to be sufficiently long compared to the longest time constatnt to be estimated |
| InputSaturation_UcloseToUmax | The input u remains saturated at its maximum |
| InputSaturation_UcloseToUmin | The input u remains saturated at its minimum |
| NegativeEstimatedTi | Negative time constant. A non-causal model is an inidication of data error usually. |
| NotPossibleToIdentifyPIDcontroller_BadInputData | The input data was tagged "bad" and could not be used for id |
| NotPossibleToIdentifyPIDcontroller_UAppearsUncorrelatedWithY | u and y are uncorrelated |
| NotPossibleToIdentifyPIDcontroller_YsetIsBad | The setpoint data provided was tagged "bad" |
| Nothing | No warnings |
| PIDControllerDoesNotAppearToBeInAuto | The PID controller does not appear to move to changes in ymeas-yset, is it in manual? |
| PIDControllerIsInCascadeModeWithFrequentSetpointChanges | The pid controller is in cascade or is otherwise repsonding to extremely frequent setpoint changes that makes id very challenging. |
| PIDControllerPossiblyInTracking | u changes, but pid model has extremely low rSquared, so it does not appear to be in control |
| RegressionProblemFailedToYieldSolution | Regression returned an error |
