制导炮弹制导控制系统设计与仿真

针对采用SINS／GPS和末端寻的复合制导的制导炮弹，采用比例导引作为中制导和末制导的导引规律．从动力学方程出发，推导出制导系统的解析表达式．在对制导系统解析表达式各个参数进行分析的基础上，设计出对高度和速度具有自适应能力的制导系统控制参数，所得的结果易于工程实现．为了实现大落角攻击目标，进行了末制导过重补设计．仿真结果表明该制导控制系统性能良好，可以精确的将制导炮弹导引到目标捕获区，实现小脱靶量大落角对目标进行攻击．

Guidance and Control System Design and Simulation for Guided Projectile

Proportional navigation(PN)is used as the guidance law for the guided projectile on which SINS/GPS and terminal homing system are adopted.An analysis formula for guidance and control system based on kinetics equation is deduced.The parameters are discussed respectively and then a simple formula is presented.It is adaptive to altitude and velocity automatically.The design is easy to implement in engineering.In order to attack the target with big impact angle,over compensation of gravity is added to the design.The digital simulation results indicate that the guidance and control system works well.It can accurately guide projectiles to the target capturing zone and attack the target with littile position deviation in big impact angle.
