• Decoupling of singular systems via P-D feedback 

      Koumboulis, F. N.; Mertzios, B. G. (1996)
      The problem of input-output decoupling of singular systems via proportional plus derivative (P-D) feedback is solved. The necessary and sufficient condition for the problem to have a solution is established. A special ...
    • Generalized Hankel matrix for the minimal realization of singular systems 

      Koumboulis, F. N.; Mertzios, B. G. (1996)
      A generalized Hankel matrix (in pencil form) is introduced. Based upon this definition the dimension of the minimal realization and the controllability and observability properties are related in a straight forward way. ...
