Robust H_∞ integrity design of networked control system with quantizing error
同时考虑量化误差的网络化控制系统鲁棒H∞完整性设计

For a class of uncertain networked control system with time-varying delay,packet dropout and quantization,taken into consideration actuator failures and finite energy disturbances,based on the model with multiple successive delays in the state,this paper gave a stability criterion for the closed-loop system with robust H∞ integrity through constructing delay-dependent and quantizing error-dependent Lyapunov-Krasovskii functional,while also gave a method of the robust fault-tolerant H∞ controller design.In addition,it discussed the maximum allowable delay and the maximum allowable quantizing error when the fault network control system operated stably.Based on this,it optimized H∞ performance index and gave a method of the optimal robust fault-tolerant H∞ controller design.The result shows that the model obtained less conservative method since the lower bound of the time-delay and appropriate free-weighting matrices being introduced,moreover without model transformation during the proof.Finally,a numerical example illustrates the effectiveness of the proposed method.
