摘　　要：军用无人机鉴定试飞任务具有高空、低温、长航时且测试数据量大、种类繁多等特点,使机载测试系统稳定性和可靠性面临重大考验。以军机设备环境试验的相关标准为依据,在机载测试系统常规架构的基础上自主设计低温特性试验,并对设备性能进行检测,数据结果反映某些模块受低温影响严重。为解决以上问题,基于模糊控制策略,该文设计一种适用于无人机机载测试系统的智能温度控制器,以仿真实验对比传统PID和模糊PID的控制效果,以飞行试验验证控制器的工作性能。结果表明,设计的机载测试系统低温特性试验能有效发现设备潜在问题,智能温度控制器能够使机载测试系统在低温环境中持续、稳定工作,满足某无人机鉴定试飞–55℃、12 h的测试任务需求,可推广应用于其他飞行器。There are many characteristics in evaluation flight test of military UAV,such as high altitude,low temperature,long endurance,large amount and wide variety of test data,which take a major test to the reliability and stability of airborne test system.According to current standards of military aircraft equipments’environmental test,a low temperature characteristic test based on the conventional architecture of airborne test system is designed independently,the performance of equipments is checked,the results show that some modules of the test system are seriously affected by low temperature.To solve the problem,based on fuzzy control strategy,an intelligent temperature controller suitable for UAV airborne test system is designed,the control effect of traditional PID and fuzzy PID are compared with simulation experiment,the working performance of the controller is verified by flight test.The results show that the low temperature characteristic test of airborne test system can effectively discover potential equipment problems,the intelligent temperature controller can ensure the airborne test system work continuously and steadily in low temperature environment,satisfies the-55℃and 12 h test needs of the UAV’s evaluation flight test,and can be extended to other air vehicles.
