Abstract:

A variable structure adaptive control system for air to air missiles with thrust vectoring control is designed. Thrust vectoring actuators are used for the missiles to get supermaneuver flight ability. The designed control law includes two control parts, i.e. the continuous control part and the discontinuous control part, which are implemented by aerodynamics and reaction jet actuators respectively. Moreover, with consideration that while the missiles are supermaneuvering, the system dynamic parameters are poorly known and rapidly changing, an adaptive estimation algorithm for the system parameter variations is proposed to simplify the control system design. Numerical simulation results are given to illustrate its effectiveness.
