Aiming at the characteristics of high-speed reentry vehicle model with parameter uncertainty and measurement noise, a robust attitude control law structure of dual loop is proposed. The attitude control law design is made by using the μ synthesis method. The weight function is optimally designed by genetic algorithm in the design , To ensure that the system has good robustness. Through the lateral design and simulation analysis of the robust controller, the validity of the design method is verified. The design process and simulation results show that this method can effectively solve the design problem of robust attitude control law of high-speed aircraft and avoid the complicated work of selecting the weight function in robust controller design process.
