  Mutually conjugated synergetic schemes are assumed to address evolution of
nonequilibrium self-organizing system. Within framework of the former, the
system is parameterized by a conserving order parameter being a density, a
conjugate field reducing to gradient of related flux, and control parameter,
whose driven magnitude fixes stationary state. We show that so-introduced
conjugate field and control parameter are relevant to entropy and internal
energy, so that self-organization effect is appeared as a negative temperature.
Along the line of the conjugated scheme, roles of order parameter, conjugate
field and control parameter are played with a flux of conserving value, and
gradients of both chemical potential and temperature. With growth of the
latter, relevant value of the entropy shows to decrease in supercritical regime
related to spontaneous flux-state. We proof that both approach stated on using
density and conjugated flux as order parameters follow from unified field
theory related to the simplest choice of both Lagrangian and dissipative
function.
