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.
