摘　　要：对三回路自动驾驶仪的工作原理及特点进行了分析.研究表明,这种驾驶仪的内回路是姿态驾驶仪,可以对静不稳定导弹进行稳定,闭环稳态传递系数不受气动参数变化的影响,驾驶仪输出对舵机零位误差不敏感,系统响应速度较带积分校正的过载驾驶仪快,且三回路驾驶仪比标准驾驶仪对噪声有较强的滤波能力.To design the three-loop autopilot properly, the characteristics and operation principle have been analyzed. It has been concluded that the inner loop of a three-loop autopilot is an attitude autopilot, it can make an unstable missile stable; missile aerodynamic coefficient change and fin control surface bias do not have effects on the steady state outputs of three-loop autopilots. Also, compared with an integration compensated acceleration autopilot, faster response can be obtained with a three-loop autopilot. A three-loop autopilot also has a better filtering response for noisy input.
