摘要
本文针对空间拦截的非线性运动学模型,通过用逆系统方法求解非线性最优控制,从理论上提出了一种全状态反馈的非线性末端导引律,且进行了仿真检验,同时与比例导引律进行了比较,结果表明该导引律性能良好。
This paper provides a nonlinear terminal guidance law by means of solving a sort of nonlinear optimal control with the inverse system method. This guidance law is based upon a nonlinear kinematical model of space interception and is in the form of globalstate feedback. The results of the simulation show that the performance of this nonlinear guidance law is quite good, it is much better than that of the classical proportional navigation.
