Robust Control Design With Matlab Access

: Use robstab to find the "robust stability margin," which indicates the percentage of modeled uncertainty the system can handle before becoming unstable.

: Use ureal for real parameters with a range (e.g., ) or ucomplex for complex uncertainties. Robust Control Design with MATLAB

: Use propagate or usample to generate a set of randomized Bode or step responses to visually inspect how uncertainty affects the time and frequency domains. : Use robstab to find the "robust stability

: Use ultidyn to represent dynamic uncertainty, often used to account for high-frequency behavior that isn't captured in the nominal model. Robust Control Design with MATLAB
