在纵向通道制导系统中给出了实现比例导引和攻角归零的控制器结构和控制参数设计方法,采用比例式过载控制和积分式过载控制分别实现了攻角归零和比例导引,并根据给定的标准弹道选择了若干特征点,利用频域法设计了控制参数,然后进行了纵向通道制导系统数学仿真,仿真结果表明,所设计的制导系统可以实现火箭助飞鱼雷位置的准确控制。

The controller structure and design method are proposed to realize attack angle tending to zero and proportional guidance for normal guidance system. The proportional and integral controls of acceleration feed-hack are used respectively to realize attack angle tending to zero and proportional guidance. Some feature points are selected on the given standard trajectory, and the controller parameters of the stability loop are designed in frequency domain. Moreover, a mathematical simulation is performed, and the result shows that such designed guidance system can realize accurate position control of the rocket-assisted torpedo.
