Abstract

An adaptive dead-zone inverse controller using a output feedback backstepping method is designed for systems with an unknown dead-zone at the input of a smooth nonlinear dynamics. It uses a new parametrization of a state observer and a new robust control law suitable for parameter projection needed for implementing an adaptive dead-zone inverse. The proposed adaptive design ensures closed-loop signal boundedness and improves system tracking performance
