Eigenvalue/eigenvector assignment for multivariable systems and further results for output feedback control

Abstract
The design procedure proposed by Srinathkumar and Rhoten for eigenvalue/eigenvector assignment is reinterpreted and its relationship to the matrix pseudoinverse is pointed out. An eigenvalue/eigenvector assignment method for output feedback control of nth-order n-input m-output (m≤n) systems is also presented. Geometric interpretation of state-space equations readily shows how many, and which, elements of the closed-loop-system eigenvector or reciprocal basis vector can be specified.
