卫星制导炸弹参数空间法控制器设计

Design of Parameter Space Method Controller for Satellite Guidable Bomb

针对卫星制导炸弹在飞行过程中存在的参数摄动问题,特别是大空域参数时变,经典控制理论所设计的控制器难以满足要求。为消除干扰,保证系统的稳定性,采用参数空间法设计卫星制导炸弹的飞行控制系统,以适应其参数的大范围的变化,提高了控制精度。对某型号卫星制导炸弹,设计了俯仰通道的参数空间法控制律,给出了卫星制导炸弹控制系统计算机辅助设计的算法。数字仿真结果表明,方法能有效地解决卫星制导炸弹参数摄动带来的控制器设计问题,增强了控制系统的稳定性和鲁棒性。

Considering the problem of parameter variety in course of flight for Satellite guidable bomb,especially time-varying characteristics of parameters,the flight control system of satellite guidable bomb has been designed in the paper by using parameter space method,the large range variation of parameters is adapted and the control precision is improved. The parameter space method control laws for pitch channels of a certain type Satellite guidable bomb is designed,and the assistant arithmetic by computer is also given. Finally the design of parameter space method controller is solved and the adaptability and robustness are enhanced by the result of simulation.
