摘要
为了解决弹道导弹扰动引力计算精度与速度的矛盾,利用模糊控制的特点,通过对模糊控制器的改进,成功将模糊控制运用于扰动引力的计算。从计算思路、基本点扰动引力的计算、分级模糊控制规则的具体改进等方面进行了详细分析,仿真结果表明:运用所提出的模糊控制方法计算得到的扰动引力与真值误差很小,而计算速度远快于分层点质量法等常规方法。
In order to solve the contradictions of precision and speed of gravity disturbance calculation,the characteristics of fuzzy control are used.Based on the improved fuzzy controller,the fuzzy control method is successfully used in the disturbing gravitation calculation.The computing ideas,basis points computation,hierarchical fuzzy control rules of specific improvement are analyzed in detail.The calculation example shows that the results biases are small by using the method of fuzzy control and the computing speed is faster than the speed obtained with conventional methods such as the stratified point quality method.
