Abstract: Based on the parametric results of state feedback eigenstructure assignment, a
parametric method to design the fault-tolerant controller is proposed. This proposed method
presents the parametric expressions of all the fault-tolerant controllers for the fault control system. The free parametric vectors in the parametric expressions offer all the design degrees of freedom, which can be further utilized to satisfy certain specifications in control system designs, such as robustness etc. An illustrative example and the simulation figures show the effect of the proposed algorithm.
