摘要
本文首先给出了容错控制器设计的一种方法，即状态反馈控制器重构设计法，然后将这种方法应用到再入弹头尾翼烧蚀时的容错控制律设计中，并设计了一个容错滚控系统，使得滚控系统能够抑制滚转异常，大大提高了命中精度。
Under the conditions of nonlinear observation equation and linear dynamic system including many kinds of disturbance resources, the paper deduces a control law of fault tolerant controller reconfiguration, and gives a set of calculation method for fault tolerant law. The scheme is designed for the reentry warhead to restrain the unusual roll. The above theory is applied to the design of a fault tolerant controller reconfiguration at reentry ablation of warhead. Numerical results are obtained, and show that the fault tolerant control law can restrain the unusual roll much better than the general one does.
