Abstract :
Hypersonic vehicle X-38 in again into existing in the process of time-varying, strong nonlinear coupling fast, uncertainty, many interference, high real time characteristics. This paper presents a robust feedback linearization of uncertain nonlinear decoupling system, establish the norm bounded uncertain system; For decoupling of uncertain system model after the constant linear feedback control and parameters of the nonlinear differential control composite control, effectively deal with the response of the system efficiency, restrain response oscillation, efficiency and stability properties of effective compromise, to avoid the through the complex control law design. Finally, the simulation results prove the effectiveness of the proposed algorithm.
