摘　　要：讨论了非线性飞控系统在实时参数化模型下的控制可重构性,给出了非线性系统的可重构条件 和伪逆法可重构条件。以自修复飞控系统为例,利用推力矢量进行了方向舵全损故障下的重构研究。仿真结 果表明,对于利用传统操纵面几乎无法重构的系统,利用推力矢量的水平偏转,重构效果较好。The control re-configurable ability of a nonlinear flight control system under the real-time parameter model is discussed in this paper. The control reconfiguration condition ( CRC ) and CRC with pseudo-inverse method are advanced. A case of a self-repairing flight control system is studied which use thrust vectoring control to replace damaged rudder. The result indicates a satisfied reconfiguration by horizontal deflection of the trust vector thruttle which is almost impossible by the other traditional control surfaces.
