Robust H_∞ Control for a Kind of Singular Networked Control System with Short Time-Delay
Fengzhi Huang · Journal of Northeastern University · 2011
H∞ control was determined for a kind of networked control system(NCS) based on a regular,impulse-free,and linear time-invariant singular control system.For the NCS with clock-driven sensors,actuators, and event-driven controllers,given an uncertain time-delay with no more than one sampling period and a limited external disturbance,the sufficient condition of the existence of dynamic output feedback H∞ control law was derived through Lyapunov theory and linear matrix inequality.A corresponding design method is also presented.Validity of the proposed approach is demonstrated by a simulation example.
