H Control in Networked Control System with Stochastic Delays and Packet Dropout Compensation

  • 摘要: 给出一个存在随机时延和数据包丢失的网络控制系统(Networked Control System,NCS)模型,并分析了其渐近稳定的LMI条件.为了降低数据包丢失对系统稳定性的影响,在系统中增加了补偿器,并建立了具有丢包补偿器和随机网络诱导时延的NCS模型.在此模型的基础上,给出了系统渐近稳定和γ次优、最优的充分条件,并且获得了系统最优H控制的输出反馈控制律.对同一算例进行Matlab仿真,结果表明具有丢包补偿器的NCS趋于稳定的速度更快.
    Abstract: A model for networked control system(NCS) with random delays and packet dropout is presented,and the linear matrix inequality(LMI) condition for its asymptotical stability is analyzed.In order to reduce the effects of packet dropout on the system,a dropout compensator is added to the system,and a model for networked control systems with stochastic delays and dropout compensators is constructed.Based on this model,the sufficient conditions for the system asymptotical stability,γ suboptimum and optimum are given,and the output feedback control law for system H optimal control is obtained.Matlab simulation is made on the same example,and the results show that the convergence rate of NCSs with packet dropout compensation is faster.
