The linearizations at low and high residual concentrations are similar but the linearization
during the transition has a significantly different DC gain and phase characteristics. At
low frequencies, the phase differs by 180 degrees, indicating the presence of either an
unstable pole or zero.
Logging the Reactor Linear Response
The Logging tab in the Bode Plot block specifies that the computed linear systems be
saved as a workspace variable.
