The technological system is influenced by external periodic force, causing an oscillation process with a frequency equal to the frequency of perturbing force, or complex periodical processes, conditioned by the non-linear characteristics of the system, as a result of which damping and forced oscillations, parametric induced oscillations and the system self-excited oscillations appear [4].
