推出了一种利用特征结构配置设计重构控制系统的新方法 .当故障后的系统满足m+r - 1≥n的条件时 ,通过重新设计一输出反馈增益阵 ,使重构后的闭环故障系统的特征值全部恢复到故障前的位置 ,特征向量也在可配置子空间中尽量接近故障前相应的闭环系统特征向量 ,从而使重构后的系统性能最大程度地恢复到故障前的系统性能 .这种方法的优点是重构系统的稳定性可得到保证 ,且计算输出反馈增益阵的算法相对简单 .应用实例和仿真结果说明本文方法的有效性 .
A new method to reconfigure the control system by using the feature configuration design is introduced.When the faulty system satisfies the condition of m + r - 1≥n, the reconfigured closed loop fault All the eigenvalues of the system are restored to the position before the fault, and the eigenvectors are also close to the corresponding closed-loop system eigenvectors in the configurable subspace as far as possible before failure to maximize the performance of the reconstructed system to the pre-fault system performance The advantage of this method is that the stability of the reconfigurable system can be guaranteed, and the algorithm of calculating output feedback gain matrix is relatively simple.The application examples and simulation results show the effectiveness of the proposed method.
