Fuzzy logic aircraft environment controller

This paper describes the development of a new fuzzy controller used for the environmental control of the aircraft cabin, either for the cockpit or the passengers´ cabin. The proposed control approach is based on the integration of several blocks representing the fuzzy regulators that control the temperature, the humidity as well as they control the air-conditioned flow. In this study, the fuzzy logic was employed in order to synthesize the air-conditioning controller for the aircraft cabin. To illustrate the fuzzy-logic controller performances, specifically developed for aircraft cabin environment, a comparative study in terms of variation smoothing, response time in transient state and flexibility are presented in this paper. The results are for Bombardier Aerospace.
