modelIntegralErrorDualBounds

Integral error with dual bounds by sign for both positive and negative errors

Extends from AixLib.Utilities.KPIs.BaseClasses.PartialIntegralErrorDualReference (Partial model for integral error with dual reference values), Modelica.Blocks.Icons.Block (Basic graphical layout of input/output block).

Information

This model is an error integrator for dual boundaries, where errors exceeding the upper limit or falling below the lower limit are integrated seperately. The boolean outputs represent the state of whether the value is outside the boundaries.

Parameters

Type	Name	Default	Description
Boolean	use_itgAct_in (from PartialIntegratorBase)	false	= true, enable activation connector; = false, disable connector, integrator continuously activated
Boolean	use_itgRes_in (from PartialIntegratorBase)	false	= true, enable reset connector
