ABSTRACT:
A system and method for automatically controlling cabin air temperature T.sub.CBN in an aircraft having a cabin and a mixed air delivery system. The mixed air delivery system provides a flow of mixed air having an actual mixed air temperature into the cabin. The mixed air delivery system comprises a hot bleed air sub-system for providing a flow of hot bleed air, a cool air sub-system for providing a flow of cool air, and an ambient air sub-system for providing a flow of ambient air. The method comprises the steps of defining a selected cabin air temperature T.sub.CBN SEL, and then controlling the flow of hot bleed air, the flow of cool air, and the flow of ambient air such that the mixed air temperature is driven toward a target mixed air temperature defined as k(T.sub.CBN SEL -T.sub.CBN)+T.sub.CBN SEL, wherein k is a gain factor.
