Buildings.Controls.OBC.Utilities.PIDWithAutotuning.Relay.Validation.Controller

Test model for a relay controller

Buildings.Controls.OBC.Utilities.PIDWithAutotuning.Relay.Validation.Controller

Information

Validation test for the block Buildings.Controls.OBC.Utilities.PIDWithAutotuning.Relay.Controller.

The input signal, sin, mimics the response of a control process. In the first half of the test period, the relay controller is disabled, its output remains unchanged from the initial values. In the rest time, the relay controller is enabled and its output changes based on sin.

Buildings.Controls.OBC.Utilities.PIDWithAutotuning.Relay.Validation.ResponseProcess

Test model for processing the response of a relay controller

Buildings.Controls.OBC.Utilities.PIDWithAutotuning.Relay.Validation.ResponseProcess

Information

Validation test for the block Buildings.Controls.OBC.Utilities.PIDWithAutotuning.Relay.ResponseProcess.

This testing scenario in this example is the same as that in Buildings.Controls.OBC.Utilities.PIDWithAutotuning.Relay.BaseClasses.Validation.TunMonitor.
