论述了耦合的或交叉轴的自动驾驶仪控制方法,这种方法不需要增加操纵响应时间及滚动通道带宽就能有效地增加气动力控制战术导弹的可用攻角范围。这种耦合控制系统的一大优点是,在存在大攻角气动力交叉耦合时,可保持足够的导弹稳定性,而需将导弹滚动到所需的方向上或增加滚动系统的带宽。通过有意地把敏感元件的信号交叉耦合到控制通道中去(即滚动敏感元件的信号耦合到方位操纵通道,反之亦然),能获得大攻角的稳定性。事实上,有意设置的通道交叉耦合部分抵消了通道间气动力耦合的不稳定作用。
A coupled or cross-axis autopilot control method is discussed. This method can effectively increase the range of available angles of attack of the aerodynamic-control tactical missile without increasing the manipulation response time and rolling channel bandwidth. A major advantage of this coupled control system is the ability to maintain sufficient missile stability in the presence of a large cross-over aerodynamic cross-coupling, with the missile rolling in the desired direction or increasing the rolling system bandwidth. By deliberately cross-coupling the signal of the sensitive element into the control channel (ie, the signal of the rolling sensitive element is coupled to the azimuthally manipulated channel, or vice versa), stability at high angles of attack can be achieved. In fact, the deliberately designed cross-coupling of channels negates the instability of aerodynamic coupling between channels.
