Abstract： In this paper, the finitehorizon mixed H∞/H2 cooperative fault tolerant control problem was investigated for a class of stochastic timevarying multivehicle systems subject to actuator faults. By solving two coupled backward recursive Riccati equations, a distributed cooperative controller was obtained to make the cooperation tracking errors satisfy a given mixed H∞/H2 performance constraints. Effectiveness of the developed strategy was demonstrated by a numerical simulation.
