摘　　要：针对高空无人机舱内环境温度,文中为机载终端机设计了一个多点智能温控器;以单片机为核心,给出了温控器的硬件电路设计方案,详细论述了单片机ADuC812的外围电路以及升温与降温控制电路的设计;软件采用以模糊算法为基本策略且带有预估模型和积分效果的模糊控制器,控制加热器和风扇工作,将机载终端机的工作温度有效地控制在发挥最优指标的范围内;仿真实验表明该系统具有良好的动态性能和较小的稳态误差,能有效克服控制振荡问题,确保对被控对象参数变化有较强的鲁棒性;将该系统应用于无人机机载终端设备中,其温度测量的有效范围为-50℃～+50℃,测量精度0.1℃,温度控制的静态误差小于等于2℃,满足应用要求。In allusion to engine temperature of high--altitude UAV （unmanned aerial vehicle）, designed a multiple--point and intelligent tempera ture controller for airborne terminal set. This system used singlechip as the core and given temperature controller＇s hardware circuit design, described peripheral circuit＇s design of singlechip ADuC812 and control circuit of heating up or cooling down in detail. Software adopted fuzzy controller with pre- diction model and integral influence based on fuzzy algorithmic approach to control the work of heater and fan, effectively controlled airborne terminal set＇s working temperature in a range that can express optimal index. The simulation experiment shows that this system has good dynamic performance and smaller steady state error, effectively overcomes the problem of control oscillation and ensures strong robustness when controlled object＇s parame- ters are changed. The system is used for UAV airborne terminal set with measurable range from --50℃ to ＋50℃ and precision 0. 1℃, the level of temperature control static error less than or equal to 2℃, meets application requirements.
