Co-design for NCS robust fault-tolerant control

NCS (networked control system) is a kind of feedback control systems where the control loops are closed through real-time control network. The existence of real-time network in the feedback control loop makes it more complex to analyse and design fault-tolerant control (FTC) of NCS. In this paper, scheduling and control co-design for the robust fault-tolerant control of NCS is studied based on robust H_infin fault-tolerant control idea. Parametric expression of controller is given based on feasible solution of linear matrix inequality (LMI). The plant IAE index is adopted to assign priority, therefore more control performance is considered while scheduling. After detailed theoretical analysis, the paper also provides the simulation results, which further demonstrated the proposed scheme
