— Function File: W = wgt1o (vl, vh, fc)

State space description of a first order weighting function.

Weighting function are needed by the H-2/H-infinity design procedure. These functions are part of the augmented plant P (see hinfdemo for an application example).

Inputs

vl

Gain at low frequencies.

vh

Gain at high frequencies.

fc

Corner frequency (in Hz, not in rad/sec)

Output

W

Weighting function, given in form of a system data structure.
