.Buildings.Controls.OBC.Utilities.PIDWithAutotuning.Relay.BaseClasses.NormalizedTimeDelay

Information

This block calculates the normalized time delay of the output from a relay controller.

τ = (γ - ρ)/(γ - 1)/(ρ*0.35+0.65),

where γ and ρ are the asymmetry level of the relay controller and the half-period ratio, respectively.
