Global robust stabilization of cascade-connected systems with dynamic uncertainties without knowing the control direction
This note addresses the global robust stabilization problem for cascade-connected nonlinear systems assuming the control direction is unknown and the system is subject to both dynamic and static uncertainties. A possible application of the main result of this note to the global robust servomechanism problem for nonlinear systems in lower triangular form is also discussed.
