Design and Simulation of BTT Missile with High-Aspect-Ratio Wing Robust H_∞ Autopilot

Journal of Beijing Institute of Technology 2007年第1期16卷 50-55页

For the strong coupling among the channels of bank-to-turn （BTT） missile with high-aspect-ratio wing, an autopilot is designed with a two loop control structure robust autopilot design methods. By the inner loop design, the question of pole-zero cancellation is solved, and the stabilization of structured uncertainty is achieved. Through the outer loop of H∞ controller design, the flying performance and robustness can be guaranteed. The nonlinear simulation results show that the autopilot designed has perfect time domain response, and can suppress bad influence of the inertial and kinematics couplings. It can make the missile fly stably in the large flying areas. The control is very effective.

The technology of bank-to-turn is an important development direction of hypersonic glide vehicles’ *** there is a strong coupling between roll channel and yaw channel when the vehicle is in rolling *** this paper,a dual decoupling fusion control method is presented based on aileron-rudder cross decoupling control and model reference global sliding mode control for the problem of *** introducing state observation,control model switching is *** precision decoupling control is realized,and at the same time,it avoids the problem of high frequency vibration and excessive *** simulation results show that the dual fusion control method based on aileron-rudder cross decoupling control and model reference global sliding mode control can make the system retain the advantages and avoid the shortcomings of them during the hypersonic glide vehicle BTT maneuvering flight,and the control performance is quite desirable.
