Abstract: For the large height span and dramatic changes in the model parameters of airlaunched cruise missile during the whole process from launching to hitting ground target, and the request for sideslip angle of BTT control, using H_∞/Mixed sensitivity design method, this paper describes the parameter variations as multiplicative uncertainty in the output, the robust controller is designed based on three-channel decoupling model of the missile. The simulation results show that the designed controller is able to ensure strong stability and well time-domain response performance to the selected different characteristic points throughout the flight trajectory of cruise missile, inhibit lateral overload effectively in the process of turning, and achieve the goal of limiting sideslip angle.
