Design of new adaptive fuzzy logic controller for nonlinear plants with unknown or time-varying dead zones

Seok-Yong Oh, Dong-Jo Park
1998 IEEE transactions on fuzzy systems  
The steady-state control resolutions with perturbing action, which are different from the ones in the transient states, are used to cancel out the unknown and/or time-varying dead-zone effects.  ...  Therefore, we can develop the fuzzy dead-zone inverse by reperturbing and adjusting the scaling gains adequately in the steady-states.  ...  If the dead-zone nonlinearity is time-invariant, the algorithm will eventually fix the steady-state errors by providing appropriate correcting control outputs.  ...
