      MRAC for multivariable plants with zero residual tracking error 

      Tao, G.; Ioannou, Petros A. (Publ by IEEE, 1989)
      In almost all model-reference adaptive control (MRAC) schemes proposed in the literature the tracking error cannot be guaranteed to go to zero in the presence of plant unmodeled dynamics and/or bounded disturbances. It is ...

      Parameter convergence of modified adaptive laws with persistent excitation 

      Ioannou, Petros A.; Sun, Jing (Publ by American Automatic Control Council, 1990)
      The effect of σ-modification on the parameter convergence and stability properties of two different adaptive laws is analyzed. It is shown that σ-modification does not alter the ideal convergence properties of the adaptive ...

      Robust adaptive control. Design, analysis and robustness bounds 

      Ioannou, Petros A.; Datta, Aniruddha (Publ by Springer-Verlag Berlin, 1991)
      Despite the publication of numerous papers and several books dealing with the design, analysis and robustness properties of adaptive control, the theory of adaptive control may appear too technical and sometimes confussing ...
