.Annex60.ThermalZones.ReducedOrder.Validation.VDI6007.BaseClasses.VerifyDifferenceThreePeriods

Information

Block that outputs satisfied = false if abs(u1-u2) > threShold within the prescribed time intervals, or satisfied = true otherwise.

Implementation

The test uses a hysteresis of plus/minus 1% in order to avoid chattering if abs(u1-u2) is near threShold.
