And the experimental tests had been carried out to verify the established model as well as the dynamic characteristics under opening loop control. 并通过实验，对所建立的动力学模型及开环控制下平台的实际动态特性进行了验证。
For the finite propulsion reentry guidance, the conventional closed-thruster equation based on open-loop control loses its way. 摘要解决有限推力模型的再入飞行器初制导问题，利用传统开环控制的关机方程达不到要求的精度。
