Convergence results for an adaptive dead zone inverse

In this paper, an adaptive dead zone inverse is proposed for control of systems containing an unknown dead zone. It is shown that the effect of the unknown dead zone on the closed-loop control system can be eliminated asymptotically if both input and output measurements of the dead zone are available. Two schemes are proposed along with their convergence and robustness analyses. © 1998 John Wiley & Sons, Ltd.
