This paper investigates the asymptotical cooperative cruise fault tolerant
control problem for multiple high-speed trains consisting of multiple carriages
in the presence of actuator faults. A distributed state-fault observer
utilizing the structural information of faults is designed to achieve
asymptotical estimation of states and faults of each carriage. The observer
does not rely on choice of control input, and thus it is separated from
controller design. Based on the estimated values of states and faults, a
distributed fault tolerance controller is designed to realize asymptotical
cooperative cruise control of trains under the dual constraints of ensuring
both position difference and velocity difference of adjacent trains in
specified ranges throughout the whole process.Comment: 12 pages, 9 figure
