Abstract :
The main results of this note establish sufficient rank conditions for local observability of nonlinear differential-algebraic equations (DAE) systems near a known trajectory associated with a given control. Verification of the observability rank condition is addressed, and the relationship with previous work on observability of DAE is indicated
