: Use ultidyn to represent dynamic uncertainty, often used to account for high-frequency behavior that isn't captured in the nominal model.
: Use robgain to determine if the system meets specific performance goals (like H∞cap H sub infinity end-sub gain) across all uncertainty scenarios. Robust Control Design with MATLAB
: Combine these elements with standard LTI objects (like tf or ss ) to create an uncertain state-space ( uss ) model. 2. Robust Stability and Performance Analysis : Use ultidyn to represent dynamic uncertainty, often
: Methods like ncfsyn (normalized coprime factor plant description) allow you to specify desired open-loop shapes to balance performance and robustness. 4. Verification and Implementation Robust Control Design with MATLAB
