      Comparison of a nonlinear adaptive controller with certainty-equivalence type adaptive controllers 

      Zhang, Youping; Ioannou, Petros A. (IEEE, 1995)
      Recently a new class of adaptive controllers for linear time invariant minimum phase plants has been proposed and analyzed. The design of these controllers is based on nonlinear tools and appears to be different from that ...

      Dominant richness and improvement of performance of robust adaptive control 

      Ioannou, Petros A.; Tao, G. (1989)
      Several recent robust adaptive control schemes guarantee stability and residual tracking errors which are "small" in the mean for any bounded initial conditions, independent of any persistence of excitation condition. Since ...

      L1-Adaptive control: Stability, robustness, and interpretations 

      Ioannou, Petros A.; Annaswamy, A. M.; Narendra, K. S.; Jafari, S.; Rudd, L.; Ortega, R.; Boskovic, J. (2014)
      An adaptive control design approach that involves the insertion of a strictly proper stable filter at the input of standard Model Reference Adaptive Control (MRAC) schemes has been proposed in the recent years. This approach ...

      Model Reference Adaptive Control for Plants with Unknown Relative Degree 

      Ioannou, Petros A.; Tao, G. (1993)
      One of the basic assumptions in stable model reference adaptive control (MRAC) that the relative degree n002A of the modeled part of the plant is known exactly and matches that of the reference model is relaxed by the ...

      Performance Analysis And Improvement In Model Reference Adaptive Control 

      Datta, Aniruddha; Ioannou, Petros A. (1994)
      Boundedness of all closed-loop signals and asymptotic convergence of the tracking error to zero or to a residual set are the criteria that have been most commonly used to characterize the performance of model reference ...

      Performance improvement versus robust stability in model reference adaptive control 

      Datta, Aniruddha; Ioannou, Petros A. (Publ by IEEE, 1992)
      The mean square tracking error criterion and the L∞ tracking error bound criterion are used to assess the performance of a standard robust model reference adaptive control schemes in ideal and nonideal situations. Controller ...

      Robust adaptive control-a modified scheme 

      Tao, G.; Ioannou, Petros A. (1991)
      A normalizing signal that does not require the knowledge of the stability margin of the unmodelled dynamics is used in robust model reference adaptive control (MRAC) for plants with an enlarged class of unmodelled dynamics. ...

      Robust model reference adaptive control for multivariable plants 

      Tao, G.; Ioannou, Petros A. (1988)
      A complete procedure for generating and analysing robust model reference adaptive control schemes for multivariable plants is developed. The procedure consists of two parts: the first part involves the characterization of ...

      What is L1 adaptive control 

      Jafari, S.; Ioannou, Petros A.; Rudd, L. (2013)
      Recently, a class of adaptive control schemes called L1 Adaptive Control (L1-AC) has been proposed and widely advertised in aerospace control for achieving fast and robust adaptation and better performance than the existing ...
