Reconfigurable Control System Design by Output Feedback Eigenstructure Assignment
Abstract：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.
