MSL 4.1.0 Regressions - Electrical and ComplexBlocks

[GallLeo]

The following models fail in result comparison.
Tested revision: f9bddf8 (2024-02-16)

Changed models, need reference update after library officer check:

• Modelica.Electrical.Machines.Examples.ControlledDCDrives.CurrentControlledDCPM
  - Reason: Erroneous initialization of armatureInverter.iDCFilter has been fixed.
  @GallLeo pls. create new reference results.
  - Updated reference files?
• Modelica.Electrical.Machines.Examples.ControlledDCDrives.PositionControlledDCPM
  - Reason: Erroneous initialization of armatureInverter.iDCFilter has been fixed.
  @GallLeo pls. create new reference results.
  - Updated reference files?
• Modelica.Electrical.Machines.Examples.ControlledDCDrives.SpeedControlledDCPM
  - Reason: Erroneous initialization of armatureInverter.iDCFilter has been fixed.
  @GallLeo pls. create new reference results.
  - Updated reference files?
• Modelica.Electrical.PowerConverters.Examples.DCAC.PolyphaseTwoLevel.ThreePhaseTwoLevel_PWM
  - Reason: Bugfix in Modelica.Electrical.PowerConverters.DCAC.Control.SVPWM
  @GallLeo pls. create new reference results.
  - Updated reference files?
• Modelica.Electrical.PowerConverters.Examples.DCAC.SinglePhaseTwoLevel.SinglePhaseTwoLevel_R
  - Note: does not fail in csv-compare, but in integral check for inverter.ac.v
  - Reason: Changed formulation of comparison in Modelica.Electrical.PowerConverters.DCDC.Control.SignalPWM
  @GallLeo pls. create new reference results.
  - Updated reference files?
• Modelica.Electrical.PowerConverters.Examples.DCDC.HBridge.HBridge_R
  - Reason: Changed formulation of comparison in Modelica.Electrical.PowerConverters.DCDC.Control.SignalPWM
  @GallLeo pls. create new reference results.
  - Updated reference files?
• Modelica.Electrical.Spice3.Examples.Spice3BenchmarkFourBitBinaryAdder
  - Reason: Model has not been touched for ages, differences are neglectible.
  @GallLeo pls. create new reference results.
  - Updated reference files?
• Modelica.ComplexBlocks.Examples.ShowTransferFunction
  - Reason: Changed the parameters of the example to get more eye-catching results.
  @GallLeo pls. create new reference results.
  - Updated reference files?

Not classified yet, needs library officer check:

• Modelica.Electrical.Machines.Examples.InductionMachines.IMC_InverterDrive
  - Reason: Bugfix in Modelica.Electrical.PowerConverters.DCAC.Control.SVPWM
  @GallLeo pls. create new reference results.
  - Updated reference files?

• @GallLeo please note: We have improved the comparisonSignals.txt in PR comparisonSignals of PowerConverters #4353 of Modelica.Electrical.PowerConverters.Examples.DCDC.HBridge.{HBridge_R, HBridge_RL, HBridge_DC_Drive}, also back-ported to maint/4.1.x in comparisonSignals of PowerConverters #4372.
  Please create new reference results for all three examples.

• Release notes check: Are all classes mentioned which could lead to result changes in user models?

@GallLeo please note: We have improved the comparisonSignals.txt in PR #4353 of Modelica.Electrical.PowerConverters.Examples.DCDC.HBridge.{HBridge_R, HBridge_RL, HBridge_DC_Drive}
Please create new reference results for all three examples.

@AHaumer The LTX run actually shows a correctness failure in Modelica.Electrical.PowerConverters.Examples.DCDC.HBridge.HBridge_DC_Drive for the variable meanCurrent.y, so that should be checked specifically before resetting the baseline to get the new variables.

@maltelenz @GallLeo
The only difference I see is at the beginning of the trajectory of meanCurrent,y.
This is caused from improvements in the block SignalPWM.
Yes the new signal is correct, and please take the new signal as reference for the future.
