航空制导炸弹制导控制律设计

根据命中精度和射程的要求，设计了某型制导炸弹的方案弹道。在滑翔段采用给定俯仰角飞行的方法，以降低马赫数，使炸弹尽快脱离跨音速飞行状态；在俯冲段采用比例导引法，导引炸弹命中目标。给出了俯仰、偏航和滚转三通道控制律，提出了控制参数的选择方法。仿真结果表明：所设计的弹道具有射程远、精度高、易实现的特点，具有较高的实用价值。

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.
