H∞ Optimal Control of Aero engine Distributed Control System with Packet Dropout Compensator

Abstract

This article proposes a compensator to overcome the instability of the aero engine distributed control system which has network time delay and packet dropout. The method models the closed-loop in the distributed control system as an asynchronous dynamical-switched system and deduces its robust asymptotic stability criterion and the sufficient solution which satisfy certain H∞ performance index. Then the corresponding design method of compensator and H∞ optimal controller is presented. The effectiveness of the proposed compensator and controller is demonstrated by final numerical example.
