This paper proposes a practical and sequential eigenstructure assignment method for designing a parametric state‐feedback controller in multi‐input linear time‐invariant systems. This approach, which sequentially shifts a prescribed set of self ‐conjugate multiple eigenvalues to the closed‐loop system, can explicitly parameterize in groups, and is very useful.Spectrum‐invariant free parametersare proposed to simultaneously deal with two problems: (i) assigning the desired correspondingeigenvectors and generalized eigenvectorswithin an admissible class, and (ii) minimizing theFrobenius normof the resulting controller gain. The shifting of the uncontrollable mode is discussed in some detail. A scheme for determining the minimum Frobenious norm of the resultant state‐feedback matrix gain is developed. Finally, a numerical example is used for illustration of the proposed method.
