摘　　要：针对北斗指挥中心在接收终端用户的短报文信息时,由于数据量过于庞大会造成网络拥塞的问题,提出了一种Fuzzy-PID主动队列管理算法。该算法将模糊理论与传统的PID控制算法相结合,解决了传统算法在面对复杂网络环境时灵活性不足的问题。实验表明,新的主动队列管理算法既具有模糊控制灵活而适应性强的优点,又具有PID控制精度高的特点,能达到传统拥塞控制所不能达到的控制效果。When the Beidou Command Center receives the short message information of the end user,the too-large data volume would result in network congestion.Aiming at this problem,a fuzzy-PID active queue management algorithm is proposed.The algorithm,in combination of fuzzy theory with traditional PID control algorithms,solves the lack of flexibility for traditional algorithms in the face of complex network environments.Experiments indicate that the new active queue management algorithm has the advantages of flexible fuzzy control and strong adaptability,including the characteristics of high PID control precision,and could achieve the control effect that the traditional congestion control couldn’t realize.
