Robust Control of Aero-engine Networked Control System with Long Time Delay

Abstract

With a focus on the problem of long time delay of aero-engine networked control system, a robust controller is designed in this paper. The model of the aero-engine networked control system considering modelling error and external disturbances is first established. Then a robust controller is designed based on Lyapunov stability theory and matrix inequality methods. To verified the effectiveness of the proposed method, numerical simulations are made and the results reflect that the proposed controller can effectively stabilize the system in a short time despite the existence of uncertainties.
