A unified framework for passive–active fault-tolerant control systems considering actuator saturation and L∞ disturbances
, Article International Journal of Control ; 2017 , Pages 1-11 ; 00207179 (ISSN) ; Haeri, M ; Sharif University of Technology
Abstract
This paper presents a unified passive–active fault-tolerant control strategy to compensate the loss of actuators’ effectiveness. The proposed approach is capable of handling the system in pre- and post-fault diagnosis intervals by passive and active approaches, respectively. The stability of the designed system is independent of the accuracy of information provided by the fault detection and diagnosis unit, however, a precise estimation could improve the conservation. Actuator saturation and L∞ disturbances effects are considered in the design stage. The trade-off between maximising the domain of attraction and minimising the effects of L∞ disturbances is tackled by developing a non-constant...
