.Buildings.Controls.OBC.Utilities.PIDWithAutotuning.SystemIdentification.FirstOrderTimeDelay.ControlProcessModel

Information

This block calculates the model parameters of a FOPTD model. Specifically, it employs Buildings.Controls.OBC.Utilities.PIDWithAutotuning.SystemIdentification.FirstOrderTimeDelay.BaseClasses.Gain and Buildings.Controls.OBC.Utilities.PIDWithAutotuning.SystemIdentification.FirstOrderTimeDelay.BaseClasses.TimeConstantDelay to identify the gain, the time constant, and the time delay, respectively.

The calculations are disabled by default. They will be enabled once the tuning period starts, i.e., triSta becomes true. The calculations complete when the tuning period ends, i.e., triEnd becomes true.

Refer to Buildings.Controls.OBC.Utilities.PIDWithAutotuning.Relay.Controller for detailed explanation of the parameters yHig, yLow, and deaBan.
