ACTIVE FAULT-TOLERANT CONTROL SYSTEM DESIGN FOR A TWO-ENGINE BLEED AIR SYSTEM OF AN AIRCRAFT

摘要

In this paper, a simplified linear model of a two-rnengine bleed air system of an aircraft is rndeveloped based on the dynamics of system key rncomponents, then an active fault-tolerant rncontroller is designed for this system using the rnpseudo-inverse method. Simulations based on rnthe linear state-space model are conducted, and rnthe results have shown that this design method rncan significantly improve system performance rnwhen faults occur on the pressure regulator of rnthe bleed air control system.
