For airbreathing hypersonic vehicle, the hypersonic cruise conditions with strong nonlinearity, parameter uncertainties, the higher requirement of control accuracy characteristics, to establish a control oriented model, and by using Lyapunov method were designed with different time scale of double loop control system. In order to solve the chattering problem of sliding mode control, this paper integrates fuzzy control with the idea of sliding mode variable structure control, and had researched the fuzzy sliding mode variable structure controller design method. This method can not only guarantee the system stability, but also restrain chattering. In the MATLAB for the control system of simulation test, the feasibility of the method is demonstrated.
