An LMI Approach to D-stable Robust H∞ Fault Tolerant Control of Uncertain Systems
In this paper, the D-stabilizable robust H ∞faulttolerant control problem is formulated in an LMI (Linear MatrixInequality) setting, in which satisfactory performance andguaranteed stability robustness are introduced. The objective isto design a controller that stabilizes an uncertain system whilesatisfying an H ∞-norm bound constraint and closed-loop poleplacement constraint in the normal condition as well as in theevent of actuator failures. To achieve such aims, a multi-objectiveapproach is used to establish a matrix inequality formulation forfault-tolerant control system design. The sufficient condition forthe existence of the controller is presented, and furthermore, aparameterized characterization of the robust controllers is givenin terms of the feasible solutions to the certain matrixinequalities. In addition, on the premise of guaranteeing thesystem integrity, the sufficient condition for the consistency of H∞-norm specification with D-stabilizable specification isderived.
