This paper presents a new approach for norm bounded continuous-time uncertain switch systems such as BTT vehicle.
Firstly, the flight trajectory has been divided into several intervals according to flight attitude. Meanwhile, the nominal
model could be obtained. Secondly, based on the linear matrix inequality (LMI), combining the guaranteed cost control
theory, the state feedback guaranteed cost control law is proposed. Then, to reduce the external disadvantage influence
on vehicle, the RBF-NN is used to compensate the intensive aerodynamic disturbance. Finally, taking BTT vehicle as the
research objective, the final results of the simulation are proved with effectiveness for the proposed design approach.
