Abstract

Åström and Hägglund (1984) suggest the relay feedback test to generate sustained oscillation as an alternative to the conventional continuous cycling technique. It is very effective in determining the ultimate gain and ultimate frequency. Luyben (1987) popularizes the relay feedback method and calls this method “ATV” (autotune variation). The acronym also stands for all terrain vehicle since ATV provides a useful tool for the rough and rocky road of system identification.
