Adaptive Dead Zone Inverses for Possibly Nonlinear Control Systems

  • Er-Wei Bai


In this chapter, an adaptive dead zone inverse is proposed for control of systems containing an unknown dead zone. Assuming that the output of the dead zone is measurable, it is shown in the chapter that the effect of the unknown dead zone on the closed loop system can be eliminated asymptotically with no assumptions on the persistent excitation of the input signal. The results do not rely on the linearity property of the system and therefore can be easily applied to some nonlinear systems.
