Reconfigurable control design based on complete parametric approach for spacecraft rendezvous

This paper studies the problem of reconfigurable fault tolerant controller design for linear time-invariant systems with measurement unavailability based on a complete parametric approach. The attention is focused on completely recovering eigenvalues of the pre-fault system by resynthesizing an output feedback controller while the restrictions on assignable eigenvalues of existing results are overcome. Further, the complete parametric method is introduced to give the parametric expressions for all output feedback matrices with the advantage of guaranteeing the stability of the reconfigured system. What's more, recon-figurable controllers for the spacecraft rendezvous system are studied as the example in cases of different measurement failure situations. Finally, numerical calculations are given and results show the effectiveness of the proposed method.
