Design of linear multivariable continuous-time output-feedback regulators

In this paper, the method of entire eigenstructure assignment (Kimura 1975, Moore 1976, Porter and D'Azzo 1917) is applied to the design of linear multivariable continuous-time output-feedback regulators. It is shown that, in the case of self-conjugate distinct eigenvalue spectra, the closed-loop eigenstructure assignable by output feedback is constrained by the requirement that the eigenvectors and reciprocal eigenvectors lie in well-defined subspaces. The method is illustrated by designing an output-feedback regulator for a third-order continuous-time system.
