H∞ Control of Networked Control Systems with Time-varying Delay and Packet Dropout
摘要
Abstract
For a class of networked control systems with time-varying delay and packet dropout,a H∞ controller is designed in order to make the closed-loop system mean square stable and meet the prescribed H∞ disturbance attenuation level.It is known that the system has data packet loss and time-varying delay from the sensor to the controller,and time varying delay from the controller to actuator.The total time delay is less than one sampling period.The uncertainty of delay is turned into the unknown parameters of the system equation so that the system is modeled as a norm bounded uncertain system.Data packet dropout is assumed to be satisfied with the Bernoulli distribution sequence with known probability.Sufficient conditions for the existence of the state feedback controller are given by linear matrix inequality and Lyapunov principle.And the controller design problem is transformed into solving the feasible solution of the linear matrix inequality.A simulation example is given to prove the effectiveness and feasibility of the design method.关键词
