Backstepping tracking control for a class of discrete-time nonlinear systems in pure-feedback form
In this paper,a new control scheme is proposed for a class of pure-feedback nonlinear discrete-time systems by using backstepping technique.This problem is considered difficult to be dealt,mainly because that the triangular structure of pure-feedback systems has no affine appearance of the variables to be used as virtual controls.After the pure-feedback form is transformed into a cascade form,the feedback tracking controller is developed by using backstepping procedure.Under appropriate assumptions,the closed-loop nonlinear discrete-time system is uniformly ultimately bounded.The stability of the close-loop system is proved based on Lyapunov theorem. Simulation studies are conducted to illustrate the effectiveness of the proposed approach.
