建立了超音速巡航导弹飞行高度的串级控制系统模型；利用最优参数整定法设计了副回路反馈补偿PD调节器；运用Matlab/Sisotool设计了主回路控制器。仿真结果表明,串级控制能较大程度地提高超音速巡航导弹飞行高度的控制性能。

The cascade control system model of supersonic cruise missile was established at first.Then,a vice loop feedback compensation PD adjuster was designed by using optimal parameter setting method and a main loop controller was designed by use of Matlab/Sisotool.The results of simulation showed that the cascade control can greatly improve the control performance of supersonic cruise missile flight altitude.
