Using Lyapunov stability theory and LMI (linear matrix inequation) method, a class of control problems of reentry vehicle model with uncertain time-varying parameters is studied based on state observer. First, the feasibility of observer is verified. , A state feedback controller is designed based on the observer to ensure the stability of the system.Finally, an example simulation of a reentry vehicle model is given to verify the effectiveness of the proposed method.
