最小化时变收敛率和节点能耗的功率调度方法
Method of power scheduling for minimizing time-varying convergence and node energy consumption
摘要
Abstract
In order to improve the stability of the closed-loop system and reduce the energy consumption of the sensor node,a method of power optimization scheduling with time-varying convergence as the performance index is studied for the closed-loop discrete networked system.According to the packet loss status of the network transmission process and the quantized output feedback data,the control unit based on the state observer is designed.A quantitative encoding strategy is designed to realize the data transmission of the system under the constraint of network bandwidth.From the new perspective of taking the time-varying convergence rate and node energy consumption as the system performance optimization index,the power scheduling algorithm is designed to minimize the given performance index under the premise of ensuring the exponential convergence in the meaning of the system mean,so as to achieve the purpose of improving the system convergence speed and saving energy consumption.The effectiveness of the proposed method is verified by the example simulation.关键词
