Adaptive Fuzzy Sliding Mode Control for a Class of Nonlinear System
Abstract: For a class of
nonlinear system with parameter perturbation and external disturbance, adaptive
fuzzy control can be used to approach the system unknown functions to reduce
the control input and the steady-state error. And an adaptive switch control
gain whose adaptive law is decreasing function is designed to weaken the system
chattering, the switch gain of estimate will increase on the basis of the
original without decreasing with the elimination of interference. If system is
interferenced many times. Against the shortcomings, this paper proposes an
improved adaptive law that can weaken the system chattering effectively while
maintaining the strong robustness. The simulation results by tests show that
this method is correct and effective.
