  • POLE ASSIGNMENT IN A SPECIFIED Circular Region FOR UNCERTAIN SINGULAR SYSTEMS
    Information & Computation, 1999
    Co-Authors: Yang Cheng-wu
    Abstract:

    In this paper, we consider the problem of pole assignment in a specified Circular Region for uncertain continuousand discretetime singular systems. The system under consideration is subjected to timeinvariant normbounded uncertainties in both the state and input matrices. The problem addressed is the design of state feedback controllers such that the closedloop system is regular, impulsefree (in the case of continuous singular systems) or causal (in the case of discrete singular systems), as well as satisfying that the finite closedloop poles are located within a prespecified Circular Region for all admissible uncertainties. The conditions for the existence of desired state feedback controllers are given and the analytic expression of expected controllers are proposed. The results can be viewed as extensions of existing results on robust pole assignment in a specified disk for uncertain statespace systems to uncertain singular systems.

  • Robust eigenvalue-clustering in a specified Circular Region for linear uncertain discrete singular systems with state delay
    Applied Mathematics and Computation, 2007
    Co-Authors: Shinn-horng Chen, Jyh-horng Chou
    Abstract:

    [[abstract]]In this paper, the robust eigenvalue-clustering in a specified Circular Region problem (i.e., the robust D-stability problem) of linear discrete singular time-delay systems with structured (elemental) parameter uncertainties is investigated. Under the assumptions that the linear nominal discrete singular time-delay system is regular and causal, and has all its finite eigenvalues lying inside a specified Circular Region, a new sufficient condition is proposed to preserve the assumed properties when the structured parameter uncertainties are added into the linear nominal discrete singular time-delay system. When all the finite eigenvalues are just required to locate inside the unit circle of the z-plane, the proposed criterion will become the stability robustness criterion. The presented criterion is mathematically proved to be less conservative than the existing ones reported very recently in the literature

  • Robust D-stability analysis for linear uncertain discrete singular systems with state delay
    Applied Mathematics Letters, 2006
    Co-Authors: Shinn-horng Chen, Jyh-horng Chou
    Abstract:

    [[abstract]]In this work, by using the maximum modulus principle and the spectral radii of matrices, a new robust D-stability (i.e., robust eigenvalue clustering in a specified Circular Region) condition is proposed to ensure that, for all admissible structured parameter uncertainties, the linear discrete singular system with state delay is regular, causal and D-stable. The proposed criterion is mathematically proved to be less conservative than the existing one reported very recently

  • Robustness of pole-assignment in a specified Circular Region
    Proceedings of TENCON '93. IEEE Region 10 International Conference on Computers Communications and Automation, 1
    Co-Authors: Jyh-horng Chou, Dau-chung Wang
    Abstract:

    A sufficient condition is proposed to guarantee robust pole location within a specified Circular Region for a linear uncertain system. The explicit bound on linear time-invariant perturbations with highly structured information is obtained. Under these allowable highly structured perturbations, both stability robustness and certain performance robustness will thus be ensured. The merit of the proposed new approach is demonstrated by a example. >

  • Robust D-stability analysis for linear discrete-time singular systems with structured parameter uncertainties and delayed perturbations
    Proceedings of the Institution of Mechanical Engineers Part I: Journal of Systems and Control Engineering, 2003
    Co-Authors: Shinn-horng Chen
    Abstract:

    AbstractIn this paper, the robust D-stability problem (i.e. robust eigenvalue-clustering in a specified Circular Region problem) of linear discrete-time singular systems with structured (elemental) parameter uncertainties and delayed perturbations is investigated. Under the assumptions that the nominal discrete-time singular system is regular and impulse free and has all its finite eigenvalues lying inside a specified Circular Region, a new sufficient condition is proposed to preserve the assumed properties when the structured (elemental) parameter uncertainties and delayed perturbations are added into the nominal discrete-time singular system. When all the finite eigenvalues lie inside the unit circle of the z plane, the proposed criterion will become the stability robustness criterion. An example is given to demonstrate the applicability of the proposed sufficient condition.
