The Design Method of Fault-tolerant H8 Controller for Uncertain Linear Largescale Generalized Systems with Time-Delays

The problem of fault-tolerant stability is considered for a class of uncertain continuous large-scale generalized systems with time-delays by using Lyapunov method in this paper. The interconnected matrices can be uncertain and are assumed to be bounded. The time-delays under consideration are multiple and can be arbitrary unknown and varying but bounded. The analysis result of robust H
_∞
control is obtained for this system to be quadratic stabilizability and satisfy the given H
_∞
norm-bounded via linear immemorial state feedback from interference input to control output. The less delay dependent sufficient robust fault-tolerant stability conditions for these systems in terms of linear matrix inequalities (LMI) are derived. Based on this, the fault-tolerant controller for this system is designed.
