      ADAPTIVE CONTROL OF LINEAR TIME-VARYING PLANTS: A NEW CONTROLLER STRUCTURE. 

      Tsakalis, Kostas S.; Ioannou, Petros A. (American Automatic Control Council, 1987)
      The model reference control and model reference adaptive control problems are considered for a class of linear time-varying plants with bounded, piecewise smooth parameters. A controller structure that solves the model ...

      CONTROL SYSTEM DESIGN USING GRAPHICAL DECOMPOSITION TECHNIQUES. 

      Evans, F. J.; Schizas, Christos N.; Chan, J. (1981)
      If system state-space equations are mapped into a digraph, the algorithmic decomposition into connected subsystems, together with the application of sensitivity analysis, provides an alternative approach to quasioptimization ...

      ON THE MODEL REFERENCE ADAPTIVE CONTROL OF TIME-VARYING PLANTS. 

      Tsakalis, Kostas S.; Ioannou, Petros A. (IEEE, 1987)
      The authors have studied the problem of developing an adaptive control law that can force the output of a linear time-varying plant to track the output of a linear time-varying reference model and at the same time guarantee ...

      A Robust Direct Adaptive Controller 

      Ioannou, Petros A.; Tsakalis, Kostas S. (1986)
      This paper proposes a new direct adaptive control algorithm which is robust with respect to additive and multiplicative plant unmodeled dynamics. The algorithm is designed based on the reduced-order plant, which is assumed ...
