Abstract

This article investigates an adaptive funnel dynamic surface control (DSC) problem for a class of strict-feedback uncertain nonlinear systems with unknown control coefficients and backlash-like hysteresis input. First, a neural network (NN) state observer is constructed to estimate the unmeasurable states. Second, by utilizing the approximation ability of the radial basis function-neural networks (RBF-NNs) and the backstepping control technique, an adaptive tracking control scheme is developed, which can guarantee that all closed-loop signals are semi-globally uniformly ultimately bounded (SGUUB). Meanwhile, the DSC technique is introduced to avoid the complexity problem in the process of backstepping control. Third, by employing the funnel control (FC), the tracking error remains in a predefined funnel and converges to a prescribed interval via using a new funnel function. Finally, the superiority of the developed controller is validated by two examples.
