Implementation of Fuzzy Logic Controller in Environmental Control System (Cabin Temperature Control)

Abstract

The environmental control system (ECS) of an aircraft is responsible for many important functions such as pressurizing the cabin, controlling temperature, providing breathing air, regulating humidity and other factions those keep the aircraft fully operational. ECS is a complex system consisting of many subsystems which makes design of one controller for the whole system very difficult. In this work Fuzzy logic controller is proposed for Cabin temperature control, data has been collected for specified aircraft and utilized to design, simulate and tune the fuzzy logic controller using Matlab (FLC toolbox). Simulation results has been recorded then tuned with different tuning methods. At the end of the work it has been cleared that the fuzzy logic controller is easy to design, simulate and tuned specially when using Matlab .FLC can be considered as a better choice for complex systems than other control techniques, so it can be applied to environmental control system.
