Fuzzy control system and method for humidity of airliner cabin

The invention relates to the field of industrial process control, in particular to a fuzzy control system and a fuzzy control method for the humidity of an airliner cabin. The fuzzy control system comprises a humidity detector, an amplifier, a comparer, a differentiator, a fuzzy controller, a water supply valve and an air inlet valve. In the control method, by utilizing the fuzzy control rule, humidifying capacity and fresh air are amplified by the amplifier and then the amplified control signals are output to the water supply valve and an exhaust valve respectively, so the effective control on the humidity of the airliner cabin is realized. The system and the method ensures that a machine can complete the automatic control instead of human, convert fuzzy language into numerical operation, and can ensure that the control system has excellent adaptivity.
