Abstract:

Abstract: With the best use of the configured actuator redundancy in a system, a novel fault-tolerant control (FTC) strategy with explicit consideration of reconfiguration switching transients was presented to accommodate actuator failures. Based on the established target model, a bumpless adaptation mechanism was integrated with the reconfigurable control to smoothen the reconfiguration process and further ensure the safety of the post-fault system. Case studies of a benchmark aircraft subject to actuator failures were conducted to demonstrate the effectiveness of the proposed FTC approach.

Key words:fault-tolerant control (FTC),reconfiguration switch,actuator failures,bumpless transfer
