| Abstract: | The optimal glide trajectory and control system of combined guidance munition were studied. Glide trajectory model was established. Taking range as the performance function, considering end velocity, height and trajectory slope angle constraints, the optimal glide trajectory was solved by maximum principle of Pontryagin and conjugate-gradient method. The control variable of trajectory is limited. The mechanism of extended range was analyzed briefly. Two control system frameworks of combined guidance munition and parameters were designed. The simulation result indicates that both the two control systems can track the nominal trajectory accurately. |
