一种新型的最优末制导指令研究

A new optimal terminal guidance command

研究了一种中远程战术导弹的捷联复合制导系统最优末制导指令的设计．重点研究了增加速率陀螺和加速度计反馈时对系统的影响．基于最优控制理论的二次型性能指标，将弹体-自动驾驶仪惯性设计为三阶受控对象，导出了最优制导指令的解析表达式．数字仿真结果表明，所作分析与设计是有效的。

A strapdown combined terminal guidance system for the medium - range missile is studied and an optimal guidance command is designed. When both missile - body and autopilot are considerd as high - order controlled process, an analytic expression of guidance command is derived from the optimal control theory. The digital simulations show that the schemes can work effectively.
