Review of Fault-tolerant Control for Flight Control System
The large civil flight control system is critical for aircraft attitude adjustment and maintenance.During flight,control system faults can degrade aircraft control performance,and in severe cases,even lead to dispersion of the aircraft response,resulting in serious consequences.Deep research on the fault-tolerant control technology of the control system during flight is of great significance to improve flight control performance and guarantee system stable operation.From the perspective of control,the current fault-tolerant control methods for large civil flight control systems are summarized and summarized.Firstly,the composition of the flight control system is introduced and the main types of system faults are analyzed,including control surface faults,actuator faults,sensor faults,and process faults;Secondly,the technical progresses in fault-tolerant control of flight control system are discussed in depth,the advantages and disadvantages of various fault-tolerant control methods are compared and summarized;Thirdly,redundant resource allocation in the flight control system and its role in fault-tolerant control are described;Finally,the applications of flight control system fault-tolerant techniques in practical engineering are summarized,and the main challenges and opportunities currently facing the field of flight control system fault-tolerant control are outlined.
