Integrated Fault-Tolerant Control for Close Formation Flight
Chun Liu, Bin Jiang, Ron J. Patton, Ke Zhang · IEEE Transactions on Aerospace and Electronic Systems · 2019
This paper investigates the position-tracking and attitude-tracking control problem of close formation flight with vortex effects under simultaneous actuator and sensor faults. On the basis of the estimated state and fault information from unknown input observers and relative output information from neighbors, an integration of decentralized fault estimation and distributed fault-tolerant control is developed to deal with bidirectional interactions and to guarantee the asymptotic stability and$H_\infty$performance of close formations.
