  • Abstract This dissertation presents a thoroughgoing study on the
    stability analysis and controller design of systems with time-
    delays and perturbations. Since time-delays and perturbations
    are frequently a source of instability and are often
    encountered in various engineering systems, stability analysis
    and stabilization for the time-delay uncertain systems are
    therefore extremely improtant. Based on Lyapunov stability
    theorem, the solution of Riccati equation, and on Convex
    combination property, we propose some conditions under which
    the poles of a closed-loop system with real parameter
    uncertainties can be assigned within the specified region by
    using linear state feedback. Two types of specified regions are
    considered: (i) the region to the left of Re(s) = -σ, and (ii)
    the disk D(α,r) with center (α,0) and radius r. However, we
    consider systems with the uncertainties, which may exist on the
    system matrix and/or the input matrix, are decomposed into the
    matching and the mismatching portions. Because of the
    decomposition of the uncertainties, the system may be desgined
    to tolerate larger uncertainties. These design approaches are
    also extended to observer-controller design of perturbed large-
    scale systems. For linear continuous-time systems with time-
    delays, several new stability criteria are presented by the
    corresponding simple connected regions. From these regions, the
    stability of the system can be checked easily by inspecting the
    locations of the eigenvalues of the system matrix A_0 or its
    delay matrix A_d. In terms of the fundamental matrix and the
    Jordan canonical form of the system matrix A_0, several new and
    simple α-stability criteria for multiple non-commensurate time-
    delay uncertain systems are also proposed. Moreover, for the
    perturbed discrete-time system with multiple time-delays,
    several new conditions are propoaed to ensure that all roots of
    the characteristic equation lie inside a specified disk D(α,r
    ) with center (α,0) and radius r.
