The test signal represents the sum of harmonics with automatically tuned (self\u2010tuned) amplitudes and frequencies where the number of harmonics does not exceed the state space dimension of the plant. The self\u2010tuning of amplitudes is carried out to satisfy those requirements on the bounds of the input and output which hold true in the absence of a test signal.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Findings<\/jats:title><jats:p>In this paper, the software implementation of finite\u2010frequency identification method in the system GAMMA is considered.
