碩士 === 國立中央大學 === 機械工程研究所 === 76 === In this thesis, we first consider the stability of discrete multivariable systems subject to nonlinear time-varying model uncertainties. Based on the Lyapunov approach, stability robustness criteria are derived. Bymeans of a simple method to adjust the pole locations of the nominal closed-loop system, a design procedure for robust control is provided. The sturation possibility of the designed controllers is reduced using the porposed new control configuration. For linear time-varying perturbations, state transformatioin is proposed to improve bounds on structured perturbations as well as in unstructured perturbations. The allowable bounds for eigenvalue assignment inside a circular region are also provided for the linear time-invariant systems.
