摘　　要：针对重构故障不匹配情况下的多操纵面飞机控制问题,提出了一种基于控制分配的积分滑模主动容错方法.采用一种新的在线控制分配律简化了滑模控制律设计,设计了积分滑模控制律以保证指令重分配时系统的稳定性,在重构故障匹配和不匹配情况下,推导并证明了含控制分配律的系统整体闭环稳定性.仿真结果验证了所设计控制器的性能,有效实现多操纵面飞机的快速平稳控制.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.
