对中远程战术导弹的捷联复合制导的中制导系统进行了分析和研究。建立了目标－导弹相对运动和弹体及自动驾驶仪的数学模型。基于这一模型，应用最优控制理论，设计了考虑弹体及自动驾驶仪的惯性（即考虑制导指令至获得弹体横向加速度的动态过程，以下简称为弹体惯性）为三阶控制对象时的最优制指令。同时进行了大量的数字仿真。仿真结果表明，本文提出的方案能够可靠地工作，是适合于战术导弹的一种中制导方式，且能有效地拦截大机动目标
This paper analyzes and studies the mid-range guided missile guidance system with SINS and long-range tactical missiles. The goal - the relative movement of missiles and the mathematical model of projectile and autopilot is established. Based on the model and the optimal control theory, the inertia of the projectile and the autopilot (ie the dynamic process of taking the guidance command to obtain the lateral acceleration of the projectile, hereinafter referred to as the projectile inertia) is designed to be the third-order control target The optimal system of instruction. At the same time a lot of digital simulation. The simulation results show that the scheme proposed in this paper can work reliably and is a medium guidance method suitable for tactical missile and can effectively intercept large maneuvering targets
