Finding rapid and analytical solution to the calculation of zero effort miss (ZEM) has helped to improve the calculation speed of the predictive guidance law.

寻找快速的甚至是解析的零控脱靶量(ZEM)计算方法有助于提高预测制导方法的计算速度。

Finally, taking into consideration the trust controllability condition of the interceptor with a solid motor, the control law of ZEM is designed to determine the command trust orientation.

最后考虑固体推进拦截器的可控性约束条件设计了ZEM控制律并结合动力学方程确定指令推力方向。
