Uncertainty Analysis with Simulink Models

Simulate uncertainty effects, compute stability margins

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.
