A Short Note for the Robustness Properties of Hybrid Dead-Beat Observers
  A discussion of the robustness properties of the proposed observer with respect to measurement errors is provided for the recently proposed full-order and reduced-order, hybrid, dead-beat observer for a class of nonlinear systems, linear in the unmeasured states.
