: 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
Robust control design with MATLAB focuses on developing systems that maintain stability and performance despite model uncertainties, external disturbances, and sensor noise. The primary tool for this is the Robust Control Toolbox , which provides functions for creating uncertain models, analyzing stability margins, and synthesizing robust controllers. Robust Control Design with MATLAB
: Use ureal for real parameters with a range (e.g., ) or ucomplex for complex uncertainties. : Combine these elements with standard LTI objects
: Robust controllers often have high order. Use reduce to find a lower-order approximation that still meets performance requirements. Robust Control Design with MATLAB: | Guide books analyzing stability margins
