Buildings.Controls.OBC.Utilities.PIDWithAutotuning.SystemIdentification.FirstOrderTimeDelay.BaseClasses.Validation.Gain

Test model for identifying the gain of the control process

Buildings.Controls.OBC.Utilities.PIDWithAutotuning.SystemIdentification.FirstOrderTimeDelay.BaseClasses.Validation.Gain

Information

Validation test for the block Buildings.Controls.OBC.Utilities.PIDWithAutotuning.SystemIdentification.FirstOrderTimeDelay.BaseClasses.Gain.

This testing scenario in this example is the same to that in Buildings.Controls.OBC.Utilities.PIDWithAutotuning.SystemIdentification.FirstOrderTimeDelay.Validation.ControlProcessModel.

Buildings.Controls.OBC.Utilities.PIDWithAutotuning.SystemIdentification.FirstOrderTimeDelay.BaseClasses.Validation.TimeConstantDelay

Test model for identifying the the time constant and the time delay of the control process

Buildings.Controls.OBC.Utilities.PIDWithAutotuning.SystemIdentification.FirstOrderTimeDelay.BaseClasses.Validation.TimeConstantDelay

Information

Validation test for the block Buildings.Controls.OBC.Utilities.PIDWithAutotuning.SystemIdentification.FirstOrderTimeDelay.BaseClasses.TimeConstantDelay.

The input tOn changes from 0 to 0.1 at 0.1s, input k is constant, input ratioLT changes twice, from 0.3 to 0.4 at 0.32s and from 0.4 to 0.3 at 0.8s.
