Design of Guidance and Control Law for Aerial Guided Bomb

The principle of scheme trajectory design based on the requirement of impact accuracy and range is discussed in this paper.In gliding phase,a descending trajectory based on given pitch angle is presented to make the bomb escape from transonic flight as quickly as possible.In dive phase,proportional guidance law is adopted for guiding the bomb to the target.The control law for pitch,yaw and roll channels is proposed,and the design method of control parameters is also presented.Simulation results indicate that the trajectory has many advantages such as better accuracy,easy realization and great applied value.
