to SISO and MISO systems subject to a single tonal
disturbance.
The SFSCF method is a very low-order controller
with a high number of free design parameters. The
method shares most of the drawbacks and advantages
of the FSCF method, with a few exceptions. The
sensitivity to the measurement noise is poor in processes
subject to multiple disturbance tones and the stability
margins are very poor. However, the
computational requirements for the control algorithm
are very low. The method is the best applicable to SISO
and MISO systems subject to a single tonal
