通过对网络控制系统的结构分析，建立了带有时延和丢包的线性网络控制系统的数学模型．在此模型基础上，对二次型性能指标下的网络控制系统的随机最优控制问题进行了分析，获得了相应的最优增益和最优性能指标的表达形式．最后，通过仿真比较了不同丢包率下的网络控制系统的随机最优控制效果．Matlab仿真结果表明了随机最优控制算法的有效性和丢包率临界值的范围．
通過對網絡控製繫統的結構分析，建立瞭帶有時延和丟包的線性網絡控製繫統的數學模型．在此模型基礎上，對二次型性能指標下的網絡控製繫統的隨機最優控製問題進行瞭分析，穫得瞭相應的最優增益和最優性能指標的錶達形式．最後，通過倣真比較瞭不同丟包率下的網絡控製繫統的隨機最優控製效果．Matlab倣真結果錶明瞭隨機最優控製算法的有效性和丟包率臨界值的範圍．

Via the analysis of the structure of networked control systems , it presents the linear mathematic model with stochastic delay and packet losses .Based on the model , the stochastic control problem with quadratic criteria of the networked control systems was analyzed .The expressions of optimal gain and op-timal performance index were given .Ultimately, the stochastic control effect of networked control systems with delay and different probability of packet losses rate were compared by simulation .The simulation re-sults of Matlab show the effectiveness of the stochastic control algorithm and the range of the critical value of the packet loss rate .
