Deceleration control by the coning motion for CAV terminal guidance without velocity profile

The deceleration control by the coning motion without the velocity profile is proposed for common aero vehicle (CAV) terminal guidance, which restricted by velocity and position requisition. First, one-order approximate model of velocity and long range is derived, which transform the guidance deceleration control to closed loop guidance interrelated by terminal velocity. Velocity precision is improved by aerodynamics analysis and optimal guidance parameter design. Then, according to the characteristic of the coning motion target velocity and position precision meet the specified requirements, by orthogonal allocating the trajectory acceleration and the velocity over load. The simulation results show that, the method can achieve the high accuracy, adapt to serious disturbance and deviation without programming velocity profile beforehand and complex calculations.
