Uncertain Models in Simulink

Represent uncertain elements in Simulink^® models, linearize models with uncertainty

Robust Control Toolbox™ software provides tools to model uncertainty in Simulink. Using these tools, you can analyze how the uncertainty impacts the time- and frequency-domain behavior of the Simulink model.

The Uncertain State Space block, included in the Robust Control Toolbox block library, is a convenient way to incorporate uncertainty information in a Simulink model. For more information, see Specify Uncertainty Using Uncertain State Space Blocks.
