In this paper the problem of optimal QTR H-infinitynorm
approximation of an LTR controller with specified poles
isconsidered. A structurally predefined fixed order LTR controller
isintroduced which has the same dimension as the number of
transmissionzeros. It is shown that the design problem can be
reduced into anequivalent convex optimization problem involving
LMI which can be solvedefficiently. We demonstrate the performance
of this LTR controller bycomparing it to a functional observer
based LTR controller of the samedimension.
