摘要
提出了一种基于Gaussian势函数的模糊制导方法,完成了非合作式航天器自主交会对接及相关任务。首先根据视线坐标系建立了系统相对运动状态方程。进而应用模糊控制方法完成了非合作目标飞行器的自主交会对接任务,同时应用基于Gaussian势函数的模糊制导方法解决了动态障碍物的躲避问题。随后研究讨论了两种不同情形下动态障碍物的躲避。最后,用精确的数学模型进行了数值仿真,验证了制导方法应用于所研究问题的正确性和有效性。
A guidance control method of fuzzy logic guidance based on Gaussian potential function is proposed for the mission of autonomous rendezvous and docking with non-cooperative target spacecraft and the correlative missions.Firstly,the relative motion state equations are established regarding sight coordinate frame.And then,the mission of autonomous rendezvous and docking with non-cooperative target is accomplished by using fuzzy logic control,and the problem of dynamic obstacles avoidance is resolved by applying fuzzy logic guidance based on Gaussian potential function.Additionally,the two cases of dynamic obstacles are studied and discussed.Finally,the numerical simulation results based on a precise mathematic model show the validity and effectiveness of this guidance method.
