本文提出了精确的稳定性分析的速率控制算法中描述的执行。Eval. 2001; 43(2-3):63-94; Int. J. Commun. Systems 2001; 14(6):593-618.分析了存在控制环延迟时速率控制过程的稳定域。速率控制过程由延迟差分方程表示,并根据控制参数和控制回路延迟推导出渐近稳定的判据。分析表明,Aweya等人导出的控制增益的近似上界与本文给出的精确上界非常接近。通过在离散时间域中进行的理论计算,我们证明了随着反馈时延d的增加,控制强度(即控制增益α)必须降低,以使系统保持稳定。版权所有© 2004年约翰威利父子有限公司。
This paper presents exact stability analysis of a rate control algorithm described in Perform. Eval. 2001; 43(2–3):63–94; Int. J. Commun. Systems 2001; 14(6):593–618. The stability regions of the rate control process in the presence of control loop delay are analysed. The rate control process is represented by delay‐difference equation and the criteria for asymptotic stability are derived in terms of the control parameters and control loop delay. The analysis shows that the approximate upper bound of the control gain derived in Aweya et al. is very close to the exact bound developed here. Using theoretical calculations performed in the discrete‐time domain, we show that as the feedback time delay d increases, the intensity of control (i.e. the control gain α) must decrease in order for the system to remain stable.
