A kind of engineering trajectory oscillation eliminated control method for suborbital reentry vehicle

According to the special trajectory oscillation after initial dive and the great difficulty to feet the flight constraints during suborbital reentry, a kind of bank angle compensation trajectory control method is put forward base on the basic orbital predictor-corrector guidance algorithm. Without the compensation the trajectory pulls up too high after the initial dive, and then continues the oscillatory cycles for the rest of the trajectory. With the feedback in the bank angle, the first pull up and the phugoid oscillations are effectively damped out in the entry trajectory and all the constraints about heating rate, load factor and dynamic pressure are all satisfied.
