摘　　要：针对三通道耦合BTT导弹自动驾驶仪设计问题,提出了应用H∞控制理论对其设计的方法。该方法把俯仰、偏航及滚动通道间耦合作用看作是干扰项,这样从H∞标准状态方程形式上看,导弹模型没有了耦合,从而可以对滚动、俯仰和偏航三个通道独立进行设计。给出了应用该方法的具体步骤。通过三通道导弹控制系统联合仿真研究表明,该设计方法可行,可以很好的抑制耦合干扰,满足设计指标。A design method using H.. control theory is proposed for three-channel coupling bank-to-turn （BTT） missile autopilot. The main ideal of the method is to consider the coupling among the pitch, the yaw and the roll channels as disturbance, as a result there is no coupling in the missile model in the form of H∞ standard state function. Therefore, the pitch, the yaw and the roll channels are designed independently. The concrete steps are given in this method. Simulation of three-channel control system shows that the proposed design method is simple and feasible, and the designed autopilot is efficient for the BTT missile, because it can restrain the disturbances effectively.
