摘　　要：对遥控操纵模式的无人机来说,有效、安全着陆是其飞行品质的首要要求。研究了无人机遥控操纵模式下着陆的典型问题和关键因素,从人机闭环角度分析,建议遥控着陆阶段采用姿态控制模式。在典型的无人机地面闭环试验环境中,模拟了典型时间延迟和链路短时中断情况,让试飞员分别在速率控制和姿态控制模式下完成遥控着陆任务,并按照修订后的适应于无人机飞行的库珀-哈珀评定准则进行评价。通过试飞数据分析和飞行员评价表明:指令姿态控制模式在遥控着陆任务中具有控制精确、飞行员工作负荷小和不易产生PIO等优势。For remotely piloted UAV,landing safely and effectively is the primary and significant requirement of flying qualities. This paper investigates typical issues and key factors effecting safe landing under remote control for UAV. From the perspective of pilot-aircraft closed loop,it is suggested that attitude control method is suitable for landing phase. Remote control landing tasks under situations like time delay and data-link interruption temporarily were simulated in typical ground test environment,which are implemented in rate control mode and attitude control mode respectively by flight test pilots. And then flight test pilots evaluate the landing process according to modified Cooper-Harper rating scale applicable to UAV. The results of pilot evaluation and flight testing data analysis indicate that command attitude control mode has many obvious advantages,such as precise control,low workload for UAV＇s pilot and less opportunity for PIO and so on.
