An LMI approach to fault-tolerant control of uncertain systems

In this paper, the robust fault-tolerant control problem is formulated in an LMI (Linear Matrix Inequality) setting, in which satisfactory performance and guarantees stability robustness are introduced. To achieve both performance and stability robustness, a multi-objective approach is used to establish a matrix inequality formulation for fault-tolerant control system design which is based on the assumption that both fault effect factors and uncertainties can be of linear-fractional-transformation parameter dependence. An example of flight control system is used to demonstrates the design technique presented in this paper.
