IBR Stability, Model Reduction, and Validation

Frequency and Time-Domain Validation

C2-03 · Module outline

Evaluate a model against declared channels and disturbance scales.

Learning objectives

  • Compare frequency responses over declared bands.
  • Separate local consistency from finite-amplitude fidelity.

Concept outline

  1. Transfer matrices and cross channels
  2. Band-specific errors and output normalization
  3. Step-response errors and event windows

Experiment direction · Planned

Simulation and code experiment

Test whether a small P-channel error hides a Q-channel or modal mismatch.

Model explanations, parameter settings, runnable code, and result interpretation will be developed here.

Practice and discussion

Declare the retained channels before comparing model errors.

Worked solutions and feedback will accompany the full lesson.

Material preparation

Related notes, models, or notebooks are available and need adaptation into a web lesson and experiment.

Adapt the existing material into a lesson, a reproducible experiment, and worked practice.
