Stability Analysis of Networked Control System with Data Loss and Time Delay

데이터손실과 시간지연을 고려한 네트워크 제어시스템의 안정도 분석

Network uncertainties such as data loss and time delay can vary the stability property of networked control system. Therefore, these uncertainties must be considered first in designing networked control system. In this paper, we present a new stability analysis method of networked control system with data loss and time delay. The proposed method can determine maximum allowable time delay and minimum allowable transmission rate that preserves stability performance of networked control system. The results of the simulation validate effectiveness of our stability analysis method.
