Abstract :
The problem of robust stability in feedback control systems with real uncertain parameters and unmodeled dynamics is considered. A robust margin rm is defined, and an algorithm to calculate rm and the closely related multivariable stability margin km is developed. How robust performance for real parametric uncertainty can be handled in this framework is also shown. The result essentially provides a method to check whether or not the infinity norm of a closed-loop transfer matrix is less than a specified level over a bounded set of real parametric variations
