Decentralized Adaptive Control of a Turbofan System with Partial Communication

In this paper we develop control theoretic concepts for decentralized adaptive control with partial communication for a twin spool gas turbine engine system. Distributed / decentralized adaptive control architecture creates tangible benets from the distribution of closed-loop feedback around the engine. The idea is to control the two subsystems of the engine without any direct communication between the controllers and also without direct interference of each subsystem dynamics with other subsystem controller. This approach helps to optimize the performance of the engine subsystems separately.
