| 摘 要： | 针对巡航导弹常见的两种自动驾驶仪,即姿态自动驾驶仪和过载自动驾驶仪,进行对比研究,并分析其与比例导引律匹配时的系统制导性能.通过对其结构图及传递函数的分析可以看出过载自动驾驶仪能够实现全状态反馈,使系统响应具有很好的快速性.当和比例导引法匹配时,由于法向过载控制能够直接对质心进行控制,故其制导性能更好.通过对制导回路和自动驾驶仪匹配的三自由度仿真,结果表明采用过载自动驾驶仪的系统其制导时间短,脱靶量小,从而验证了理论的正确性.

| Abstract: | The characteristics of two types of autopilots of cruise missile,namely the attitude autopilot and the overload autopilot,and the system's performance when they combined with PNG law,are analyzed. According to structure blocks and the transfer functions,all the state can be fed back in the overload autopilot,so its system response is more quickly. Combined with the PNG law,the overload autopilot controls the missile's centroid directly. This makes the guidance capability better. Through simulating the guida... |
