At the beginning of 1990"s, backstepping was developed by Kokotovic and his copartners, it is a kind of circulative nonlinear design method that uses systematic way to construct feedback method and simultaneous correlative control Lyapunov function and so more and more scholars pay attention to it. Because it has very good flexibility, people can use "good" nonlinear item through introducing nonlinear damping to control "bad nonlinear item. Now backstepping design method is one of the most effective methods to settle control problems in nonlinear system with uncertainty.
