Output feedback adaptive fault‐tolerant compensation tracking control for linear systems based on the closed‐loop reference model

Abstract

SummaryThis paper investigates the problem of output feedback adaptive compensation tracking control for linear systems subject to external disturbances and actuator failures including loss of effectiveness faults and bias faults. The impact of actuator faults on the transient performance of systems can be mitigated predicated on the closed‐loop reference model with an additional degrees of design freedom. Using the estimation information provided by the adaptive mechanism, an output feedback adaptive fault‐tolerant control strategy is developed to track closed‐loop reference model systems. It is shown that all the signals of the resulting closed‐loop system are bounded. Finally, simulation results are given to demonstrate the effectiveness of the proposed fault‐tolerant tracking control method.
