摘要
In this note, we present a new scheme to design adaptive controllers for uncertain systems preceded by unknown dead-zone non-linearity. The control design is achieved by introducing a smooth inverse function of the dead-zone and using it in the controller design with back-stepping technique. For the design and implementation of the controller, no knowledge is assumed on the unknown system parameters. It is shown that the proposed controller not only can guarantee stability, but also transient performance.
