【摘要】:针对无人机自主飞行过程中,受空中非协作移动目标威胁较大,且空中移动威胁存在高机动性的特点,提出一种预测移动威胁情况下的无人机防撞控制方法,该方法采用交互多模(IMM)算法预测移动威胁的运动状态,同时利用滚动时域控制(RHC)思想建立无人机运动控制模型,构造有约束目标函数,运用微分进化算法(DE)求解目标函数,获取最优控制量,输入控制模型,完成防撞机动控制。仿真结果表明,该方法可以有效解决空中多架航空器同时入侵的防撞问题。
[Abstract]:In this paper , we propose a method to predict the motion state of an unmanned aerial vehicle under the condition of airborne non - cooperative movement , and to propose a method to predict the motion state of the unmanned aerial vehicle under the condition of moving threat . The method adopts the interactive multi - mode ( imm ) algorithm to predict the motion state of the moving threat . At the same time , the object function is established by using the rolling time domain control ( RHC ) idea , the optimal control quantity is obtained , the input control model is used to complete the anti - collision maneuver control . The simulation results show that the method can effectively solve the problem of collision avoidance at the same time of the aerial multi - frame aircraft .
