摘要
针对空空导弹的导引问题,基于模糊逻辑,提出一种新型智能导引律。将导弹与目标的接近速度以及导弹的视线角速度作为模糊控制器的输入,指令加速度作为输出,并在传统的模糊逻辑控制基础上引入了一个非线性变论域函数,从而实现动态改变模糊变量论域的目的。在此基础上,采用V isua l C++和O penGL来设计空战的三维可视化仿真平台,并实现了逼真的动画效果。
Based on the fuzzy logic,a new proportional navigation law is given for the navigation of air-to-air missile. The line of sight （LOS） rate and the close speed between missile and target are inputs of fuzzy controller. The output of fuzzy controller is the commanded acceleration. Based on the conventional fuzzy logic control,a nonlinear function is imported to change the region. The nonlinear function can be changed with the input variables. So the dynamic change of fuzzy variable region is achieved. Based on it, the paper uses Visual C＋＋ and OpenGL to design a 3-D visualization simulation platform of air-battle,and works out the realistic animation.
