The application of fixed-time control in nonlinear pure-feedback systems is studied.To solve the problem that the traditional backstepping method cannot deal with the pure-feedback system,an unconventional coordinate transformation is introduced.Based on Lyapunov stability theorem,it is proved that the proposed control algorithm ensures that the system tracks the given signal within fixed time,and the convergence time is independent with the initial state of the system.Finally,the effectiveness of the proposed algorithm is verified by two simulation examples.
