摘要
研究了一类时变对象网络控制系统的建模和稳定性问题,推导了该类网络控制系统的时滞连续时间数学模型,并基于李雅普诺夫第二法,分析了系统的渐近稳定性,得到了系统稳定运行的最大允许时延。最后,通过实例分析证实了本文所提理论的有效性,以及稳定判据的可行性。
This paper studies the model establishment and stability analysis of the network control system of classⅠtime-vary- ing object, deducts the time-lag continuous-time math model of such network control system,and analyzes the asymptotic stability of the system based on Lyapunov No.2 method to get the maximum allowed time-lag for the stable running of the sys- tem.At last,analyze and prove the effectiveness and the feasibility of this theory.
