Robust adaptive fault‐tolerant control of uncertain linear systems via sliding‐mode output feedback

摘要: Summary This paper is concerned with the robust adaptive fault-tolerant compensation control problem via sliding-mode output feedback for uncertain linear systems actuator faults and exogenous disturbances. Mismatched disturbance attenuation performed H∞ norm minimization. By incorporating matrix full-rank factorization technique sliding surface design successfully, total failure of certain actuators can be coped with, under assumption that redundancy available in system. Without need a fault detection isolation mechanism, an mode controller, where gain nonlinear unit vector term updated automatically to compensate effects faults, designed guarantee asymptotic stability performance closed-loop systems. The effectiveness proposed method illustrated B747-100/200 aircraft model. Copyright © 2014 John Wiley & Sons, Ltd.
