摘　　要：目前的载人航天器温湿度控制系统回路中未设回热换热器或电加热器,结构简单可靠,但有时不能满足除湿要求,是"优先控制温度"的空气参数处理方法。针对该温湿度系统,分析其热湿耦合机理,提出采用"优先控制湿度"的最优预测控制策略,利用观测数据在线动态估计热湿负荷并预测舱室温湿度变化趋势,结合优化目标函数,获得最优的冷凝空气处理风量,从而实现温湿度最优控制,保证航天员热舒适性。仿真结果证明了该控制策略的有效性。Air parameters control usually is a kind of ＂temperature priority control＂ method because of no regeneration heat exchanger or heater in its Temperature and Humidity Control Subsystem （THCS）. The merits of this THCS are simple structure, high reliability, but its disadvantage is humidity could not be controlled well all the time. So a control strategy of ＂＇humidity priority control＂ was put forward to overcome the disadvantage, and its realization method was given. This method used the measured data to predict the change of temperature and humidity, and then realized the optimal predicted control for aircraft cabin. The simulation results show that the control strategy can ensure the temperature and humidity effectively, and at the same time it also can ensure the heat comfort.
