Fault-tolerant control methodology based free-weighting matrices of multi-variable NCSs

The issue of fault-tolerant control for uncertain continuous-time multi-variable networked control systems with actuators failure is researched, where its network transmission is connected with network-induced delay and packet dropout. The complete mathematical model is derived. And the sufficient condition for asymptotical stability is analyzed and the maximum allowable delay conditions for systems are derived by using Lyapunov stability theory combined with free-weighting matrices techniques. The efficacy and feasibility of the proposed methods is shown by presenting simulation results from multi-variable networked control example with uncertainty.
