多时滞无线通信网络的功率和速率最优跟踪

     

摘要

The hot problem of the power and rate control of wireless communication networks was investigated.In view of the fact that traditional power and rate control methods for wireless communication networks do not simultaneously consider the state delay and the input delay, so the existing algorithms for power and rate control can not guarantee the networks'' optimal output tracking performance, a new model for wireless communication networks was reestablished under considering of multiple time delay, thus a model for power and rate control containing different state delay and input delay was obtained.And then, an optimal power and rate tracking algorithm for wireless communication networks with multiple time delay was presented, which can guarantee the optimal output tracking performance of the networks.Finally, the algorithm was simulated through the Simulink software.The simulation results show that the proposed algorithm has the good control performance.%研究了无线通信网络的功率和速率控制这一热点问题.针对传统的无线通信网络模型并没有同时考虑状态时滞和输入时滞,已有的功率和速率控制算法也不能保证系统具有最优输出跟踪性能的情况,重新建立了无线通信网络的模型,在建模过程中考虑了多时滞,得到了含有不同的状态时滞和输入时滞的功率和速率控制系统模型,在此基础上,研究了一般形式的多时滞模型的时滞补偿算法,并将该算法应用在提出的多时滞模型中,给出了无线通信网络功率和速率的最优跟踪控制律.经过计算机仿真验证,提出的最优控制律具有良好的控制性能.
