Finite-Time Adaptive Fuzzy Control for Nonlinear Systems with Unknown Backlash-Like Hysteresis

Abstract This study considers the tracking control problem of nonstrict-feedback nonlinear system with unknown backlash-like hysteresis, and a finite-time adaptive fuzzy scheme is developed to address this problem. More precisely, systems are employed approximate nonlinearities, design difficulties caused by nonlower triangular structure also overcome using property systems. Besides, effect hysteresis input compensated approximating an intermediate variable. With aid stability theory, proposed algorithm could guarantee that error converges smaller region. Finally, simulation example provided further verify above theoretical results.
