英文摘要：

For a class of uncertain nonlinear systems with strict feedback structure, the non-smooth robust control is investigated. Under certain assumptions, robust non-smooth control laws are designed based on the backstepping design approach. The robust stability of the closed-loop systems is proved. The proposed method is applied to the terminal guidance of flight vehicles. Non-smooth terminal guidance laws are designed. The numerical simulation is carried out. The simulation results show the effectiveness of the proposed method.
