| 摘 要： | 在防空导弹的发射过程中,需要在给定的响应时间内确定最优轨道,导弹沿此轨道在预定的时间飞达预测遭遇点.为了轨道优化的实时计算,构造了一类梯度投影下降算法,并且给出实际应用的具体步骤.对防空导弹运动的一个数学模型的数字仿真结果表明应用这些算法可以达到很高的控制精度.

| Abstract: | In the execution of launch of the air defence missie,it is needed within a fixed response time to determine the optimal trajectory,along which the missile flies through the predictive rendezvous at the predictive time.The gradient projection algorithms are constructed for the real-time computation of trajectory optimization,and the concrete steps of the algorithms are also given.The digital simulation results for a mathematical model of motion of the air defence missile show that the sufficient high control accuracy can be achieved with these algorithms. |
