摘要/Abstract

摘要： 无线通信网络中现有功率控制通常采用基于时间的反馈机制，存在效率低和反馈信道资源浪费的问题，对此，将功率控制算法进行控制论建模，利用控制理论方法，引入事件触发机制以取代基于时间的反馈机制，从而降低功率控制反馈的执行次数，继而减少反馈信道资源的使用.在此基础上，设计了一种事件触发功率控制算法，通过理论分析验证了算法具有渐近稳定性，并进行了事件触发芝诺效应分析，分析结果表明，所设计事件触发机制的相邻2次触发时间间隔存在非零下界（即不存在芝诺效应）.最后利用数值仿真验证了所设计事件触发功率控制算法的渐近稳定性以及验证了芝诺效应并不存在.

Abstract: The existing power controls in wireless networks usually uses time-based feedback mechanism that has the problems of low efficiency and waste of feedback channel resources. The power control is modeled by control-theoretic methods, and the event-triggered mechanism is introduced so as to reduce the execution times of power control feedback and thus reduce the use of feedback-channel resources. The study integrates the event-trigger mechanism developed in control field into the power control algorithm, designs an event-triggered power control algorithm, analyzes, and verifies the stability of the algorithm. The focus is also on the event-triggered Zeno effect analysis. Simulations verify that the designed power control algorithm is the asymptotic stable and the Zeno effect does not exist.
