为了提高导弹制导律的性能,研究了一种新的模糊扩展比例导引方法。在模糊扩展比例导引设计中,以视线角速度和视线角加速度为输入,通过输入的归一化处理和模糊制导指令运算得到基准的模糊控制指令调节因子,按照导弹最大法向加速度和指令调节因子形成制导指令。仿真结果表明,与传统的比例导引比较,提出的模糊扩展比例导引抗目标机动的能力强,控制能量要求低,脫靶量小。

In order to improve the performance of missile guidance law, a new fuzzy extended proportion guidance law was researched. The line of sight (LOS) angular rate and the LOS angular acceleration were used as the controller inputs. By means of normalizing the inputs and fuzzy logic calculation, the instruction regulating factors can be acquired. According to the max normal acceleration and instruction of regulating factors, a guidance instruction was obtained. Compared with traditional PNG laws, the simulation demonstrates that the fuzzy controller acquires higher impact accuracy with lower control.
