Research on intelligent control algorithm for liquid antenna
摘要
Abstract
A reconfigurable liquid antenna model is designed to meet the needs of rapid recovery of communication capability under emergency conditions.On the basis of the model,the design method and intelligent control algorithm for liquid antenna are studied in depth.Firstly,the neural network algorithm is used to establish the mapping relationship between the electromagnetic performance parameters and the physical parameters of the liquid antenna,and the liquid temperature,height,cross-sectional radius and conductivity of the liquid antenna are predicted according to the designed performance index,and the simulation control system is designed for the reconfigurable physical parameters.By analyzing the operating characteristics of the system,the feasibility of introducing PID algorithm for control is illustrated.The particle swarm optimization(PSO)algorithm is introduced to set the PID parameters.In view of the shortcomings of the traditional PSO algorithm,the LAIPSO algorithm is proposed.In the LAIPSO algorithm,the ICMIC chaos mapping is fused on the basis of the traditional PSO algorithm and the Lévi flight strategy is introduced.In addition,the LAIPSO algorithm realizes the adaptive update of the inertia weight and adaptation of learning rate.By selecting six test functions,the LAIPSO algorithm is subjected to comparison experiments,which shows the superiority of the algorithm in solving the single-peak and multi-peak problems.Finally,taking the prediction of the physical parameters of the liquid antenna as the control objective,comparative experiments are carried out,which proves that the LAIPSO algorithm has a good tuning effect on PID parameters.关键词
