Abstract:
An important problem in H_infinity-control is the design of a
controller that minimizes the H_infinity-norm of a closed-loop transfer
matrix, multiplied by a suitable weighting function which reflects
different performance requirements over different frequency bands.
Often, these are competing requirements, and in this paper, we show
how we can efficiently compute tradeoffs between them using a simple
application of tangential Hermite-Fej'er interpolation theory.
