Abstract :
This paper considers the problem of passing from a linear time-invariant high order controller designed for a linear time-invariant plant (of presumably high order) to a low order approximation of the controller. The approximation problem is often best posed as a frequency weighted L¿ approximation problem. Many different controller representations are possible, giving different performance of the various reduction algorithms.
