H∞ fault tolerant control for Networked Control Systems with packet loss

In this paper, a fault tolerant control strategy for a class of Networked Control Systems (NCS) with data packet loss between sensor and controller is addressed, in which actuator continuous gain fault is considered. By assuming the packet loss bounded, we model the NCS as a switched system and the control gain can be obtained by solving a linear matrix inequality optimization problem. Furthermore, we consider the controlled plant with external energy-bounded disturbance and design a robust H

fault tolerant controller. A numerical example is given to illustrate the effectiveness of the proposed design method.
