Abstract: In this paper, an integral sliding model was proposed based control allocation scheme for multiple effector plane in fault tolerant control when restructure fault unmatched. A new on-line control allocation method was proposed to predigest design process of siding model control law. The integral siding model control law was designed to ensure system stability in commands reallocation. The stability of closed loop system was proved with restructure fault match and unmatched. The simulation results show the better performance of designed controller in speed control of multiple effector plane.
