Research on fault diagnosis of temperature control system in aircraft electronic equipment cabin

Abstract

The environmental temperature difference of the electronic equipment cabin was too large, which influenced the performance of the airborne electronic equipments and the whole aircraft, even brought severe accidents. Based on the study of the fault modes of the temperature control system in aircraft electronic equipment cabin, a fault diagnosis model based on the observers of the aircraft temperature control system were proposed in this paper, and the simulation analysis under various conditions is earned out. The simulation results showed that the proposed model was validity and feasibility.
