: Use ultidyn to represent dynamic uncertainty, often used to account for high-frequency behavior that isn't captured in the nominal model.
Before designing a new controller, you can analyze how much uncertainty your current system can tolerate. Robust Control Design with MATLAB
: Use wcgain to identify the specific combination of uncertain parameters that results in the worst performance. 3. Controller Synthesis Techniques : Use ultidyn to represent dynamic uncertainty, often
: 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. Robust Control Design with MATLAB
: 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
