      A graph theoretic approach to multivariable control system design 

      Schizas, Christos N.; Evans, F. J. (1981)
      A graph theoretic approach is described for the design of multivariable control for large systems as an alternative to geometric methods. An example is given f⊙r a distillation column to demonstrate the technique, with a ...

      MIMO disturbance and plant uncertainty attenuation by feedback 

      Djouadi, S. M.; Charalambous, Charalambos D. (2002)
      This paper investigates the ability of feedback to reduce plant and disturbance uncertainties in the MIMO case, by solving two fundamental problems posed by Zames in the late seventies. The approach used here is Banach ...

      Robust switching adaptive control of multi-input nonlinear systems 

      Kosmatopoulos, Elias B.; Ioannou, Petros A. (1998)
      During the last decade a considerable progress has been made in the design of stabilizing controllers for nonlinear systems with known and unknown constant parameters. New design tools such as adaptive feedback linearization, ...
