Robust Control Toolbox™ software provides tools to model uncertain dynamics in Simulink®. Using these tools, you can analyze how the uncertainty impacts the time-domain and frequency-domain behavior of a system modeled in Simulink.
Robust Control Toolbox software lets you model and analyze uncertain dynamics in Simulink.
Use the Uncertain State Space block to represent uncertain elements in a Simulink model.
Simulate uncertain systems using nominal values or samples within the uncertainty range.
For simple models with few uncertain variables, you can vary uncertainty values on a block-by-block basis.
For models with a large number of uncertain variables or multiple Uncertain State Space blocks, you can vary multiple uncertainty values simultaneously.
Compute classical and disk-based gain and phase margins of a control loop modeled in Simulink.
