Non-fragile controller design via /spl mu/ synthesis

This paper proposes a design method for non-fragile controller via /spl mu/ synthesis. The non-fragile controller is such that the closed-loop system is stable and has an H/sub /spl infin// disturbance attenuation bound. An example in hydroelectric generating speed system is provided to illustrate the design procedure.
