一种拦截机动目标的最优制导律设计

引入伪控制变量的概念,建立了线性化的描述导弹与目标相对运动的状态方程.应用线性二次型最优控制理论和改进剩余时间的计算方法,提出了一种拦截高机动目标的最优制导律.通过与比例导引律在平面拦截过程中的仿真结果对比分析,表明所提出的最优制导律在拦截机动目标时更为有效.

An Optimal Guidance Law for Intercepting Maneuvering Targets

Using the concept of pseudo control variable,a linear kinematical state equation is constructed which describes the relative motion between the missile and the target.By improving the time-to-go algorithm,an optimal guidance law is developed based on the theory of linear quadratic optimal control theory.Using the designed optimal guidance law and PN,the computer simulations have done for the interception,and the results show that the designed optimal guidance law has better performance than PN while interce...
