充分条件

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(subscript ∞) optimal control is obtained.

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。
