The paper derives a condition that allows construction of the σ-differential fields for nonlinear control systems, described by the set of input–output (i/o) higher-order delta-differential equations, defined on a homogeneous time scale. This condition is related to the submersivity assumption of the extended system, associated with i/o equations, but is formulated directly in terms of i/o equations.
