Performance evaluation in active fault tolerant control systems

In this paper, we address the problem of incorporating the notions of performance evaluation and degraded mode operation in an active fault tolerant control system (AFTCS) scheme. This problematic is addressed under a multi-criterion optimization framework, which allows us to consider several design performances. The proposed approach is composed of two principal stages. The first one deals with the detection and isolation of the failed component while the second one is dedicated to the control reconfiguration mechanism. The control reconfiguration method developed in this work comports two parts: performance evaluation and gain scheduling modules. In this paper, we mainly focus on the reconfiguration algorithm. A simulation example is given to illustrate the proposed approach
