  title={Existence Conditions for Functional Observability From an Eigenspace Perspective},
  author={Les S. Jennings and Tyrone Fernando and Hieu Minh Trinh},
  journal={IEEE Transactions on Automatic Control},
Two theorems on conditions for nonexistence and for existence, of built functional observers, from an eigenspace perspective are presented and proved. One more theorem on Functional Observability in terms of constructed products of matrices A,C and L0 is also presented. This theorem provides an easy way to check Functional Observability before proceeding with the design of functional observers. The existence and the nonexistence theorems are used to unify previously reported theorems on… CONTINUE READING
