: Use robstab to find the "robust stability margin," which indicates the percentage of modeled uncertainty the system can handle before becoming unstable.
: You can incorporate uncertain blocks directly into Simulink models for non-linear simulation and use the Control System Tuner to tune robust, fixed-structure controllers. 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 robstab to find the "robust stability
