Adaptive Control of a Class of Nonlinear Systems with Unknown Dead-Zones

Abstract An adaptive control design is proposed for systems with an unknown dead-zone at the input of a smooth nonlinear dynamics which can be transformed into the parametric-strid-feedback form . The adaptive controller contains an adaptive dead-zone inverse to cancel the dead-zone and is designed using the backstepping method for adaptive nonlinear control. The adaptive control scheme ensures closed-loop signal boundedness.
