Research on Tossing-Orientation Scheme of Over-the-Shoulder Launch and Control Technology

Abstract

Aiming at over-the-shoulder launch implementation for air-to-air missile, which is assured to be equipped with lateral thruster, a novel scheme namely tossing-orientation is proposed. Firstly, disadvantages of existing turning scheme are analyzed briefly, then a novel concept of over-the-shoulder launch scheme called tossing-orientation, as well as its implementation procedure, is put forward. In order to deal with challenge of attitude control in the scheme, a missile autopilot introducing control feedback based on phase plane is designed which can suit the characteristic of the lateral thrust device, and the asymptotically stabilization of the controller is proved. Digital simulation results show that the designed scheme can effectively improve the turning performance of air-to-air missile.
