• Robust Control of Linear Time-Invariant Plants Using Periodic Compensation 

      Khargonekar, Pramod P.; Poolla, Kameshwar; Tannenbaum, Allen R. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 1985-11)
      This paper considers the use and design of linear periodic time-varying controllers for the feedback control of linear time-invariant discrete-time plants. We will show that for a large class of robustness problems, periodic ...
    • Stabilization of Time-Delay Systems Using Finite-Dimensional Compensators 

      Kamen, Edward W.; Khargonekar, Pramod P.; Tannenbaum, Allen R. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 1985-01)
      For linear time-invariant systems with one or more noncommensurate time delays, necessary and sufficient conditions are given for the existence of a finite-dimensional stabilizing feedback compensator. In particular, it ...
    • Weighted Sensitivity Minimization for Delay Systems 

      Foias, Ciprian; Tannenbaum, Allen R.; Zames, George (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 1986-08)
      In this note we discuss the H ∞ sensitivity minimization problem for linear time-invariant delay systems. While the unweighted case reduces to simple Nevanlinna-Pick interpolation, the weighted case turns out to be much ...
