Abstract :
Approximation of rational matrix functions plays an important part in the /spl mu/-synthesis algorithm of robust controllers if the plant is subject to repeated uncertainties. Algorithms for approximation of rational matrices/factors to data are reviewed and practical issues are discussed. The methodology is illustrated by the design of a robust gain-scheduling controller for a linear time-varying system.
