Buildings.Controls.OBC.Utilities.PIDWithAutotuning.Relay.BaseClasses.Validation.HalfPeriodRatio

Test model for calculating the half period ratio

Buildings.Controls.OBC.Utilities.PIDWithAutotuning.Relay.BaseClasses.Validation.HalfPeriodRatio

Information

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

This testing scenario in this example is the same as that in Buildings.Controls.OBC.Utilities.PIDWithAutotuning.Relay.BaseClasses.Validation.TunMonitor. The lengths of the on period and the off period are sampled at 0.9s to calculate the half period ratio.

Buildings.Controls.OBC.Utilities.PIDWithAutotuning.Relay.BaseClasses.Validation.OnOffPeriod

Information

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

This example considers a relay switch output from a relay controller, relSwi.

At 0.06s, relSwi changes from On to Off.
At 0.7s, relSwi changes into On.
At 0.86s, relSwi changes into Off.

Test model for a sampler with a reset and a threshold

Buildings.Controls.OBC.Utilities.PIDWithAutotuning.Relay.BaseClasses.Validation.SamplerWithResetThreshold

Information

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

This example considers a real input, u, and a boolean input, resSig

At 0.5s, u changes from 0 to 1, triggering the sampling;
At 0.9s, resSig changes into On, triggering the reset.

Buildings.Controls.OBC.Utilities.PIDWithAutotuning.Relay.BaseClasses.Validation.TuningMonitor

Test model for the tuning period management

Buildings.Controls.OBC.Utilities.PIDWithAutotuning.Relay.BaseClasses.Validation.TuningMonitor

Information

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

At 0.1s, the length of the on period becomes 0.1s, triggering the tuning period to start.
At 0.7s, the length of the off period becomes 0.5s.
At 0.9s, the length of the on period changes from 0.1s to 0.9s while that of the off period remains 0.5s. This triggers the tuning period to end.
