中文摘要 |
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. |
英文摘要 |
A new method for designing reconfigurable control system by using eigenstructure assignment is proposed. Under the condition m+r-1≥n, the eigenvalues of the reconfigured closed-loop fault system can completely recover those of the original system by resynthesizing a new output feedback gain matrix, and the corresponding eigenvectors of the former is assigned in assignable subspace as close to those of the latter as possible. So the performance of the reconfigured system may recover the original one to a maximum extent. The advantage of the proposed method is that the stability of the reconfigured system can be guaranteed, and the algorithm for calculating the output feedback gain matrix is relatively simple. The illustrative example and simulation results demonstrate the effectiveness of the proposed method. |
