摘　　要：针对国际民航组织(ICAO)规定的Ⅲ级气象条件下飞机的自动着陆要求,在某型飞机自动着陆侧向控制系统的基础上,主要兼顾航迹跟踪精度和鲁棒性要求,设计了飞机自动着陆过程中抗偏流机动控制律。利用Matlab/Simulink建立所设计的自动着陆系统动态数学模型并进行仿真,同时对控制系统的稳定性和控制精度进行分析。仿真结果与分析表明,抗偏流机动控制律的设计使接地时的偏流角满足Ⅲ级着陆标准的技术要求,研究成果为获得该类运行的批准提供了重要参考。To our knowledge, it is imperative for an automatic landing system in the Category Ⅲ weather condition to have a decrab control unit. Therefore we design a decrab maneuver control law for the automatic landing of a certain civil airplane in accordance with the International Civil Aviation Organization （ICAO） standards under the Category Ⅲ weather condition, taking into account its path precision tracking and robustness. The decrab maneuver control law is given in Eq. （2）. We then establish the dynamic mathematical model of the designed automatic landing system and simulate the design with the MATLAB/Simulink to verify whether our design can satisfy the landing requirements under the Category Ⅲ weather condition and analyze the stability and control accuracy of the landing control system. The simulation results, given in Figs. 6 through 9, and their analysis show preliminarily that with the decrab maneuver control law we designed, the crab angle, roll angle and sideslip angle of the airplane can meet the landing requirements under the CAT m weather condition.
