... sec. If the working point lies deep enough within the stability region, then we can say that this contour is very likely to be "stable", that is, relatively small changes in the characteristics of the control object can not make the circuit unstable and cause self-oscillation. Dimensions of the "stability area" depend on the current settings of the PID = regulator. Thus, the stability graph gives the user a graphical representation of the degree of "instability risk" of the circuit at the given controller settings. Frequency analysis Frequency (spectral) analysis, that ...
