碩士 === 國立臺灣海洋大學 === 輪機工程學系 === 107 === In this thesis, the Gain-Scheduled (GS) controller design problems for Linear Parameter Varying (LPV) system subject to pole-assignment are discussed and investigated. Because the linear parameter time varying model can effectively and completely describe the uncertain system, the discrete-time GS controller design methods are developed for the model. In this thesis, a pole-assignment method is applied to achieve the transient response. And, the controller of the required characteristics is designed by GS control technology. To achieve the above object, some sufficient conditions are derived via the Lyapunov functions. Besides, the external disturbance is considered for extending the complexity of control problems LPV system. Moreover, the passivity theory is applied to discuss the effect of external disturbance on the LPV system. With the same way, the Lyapunov function is applied to derive some sufficient conditions. Then, the derived sufficient conditions are converted into Linear Matrix Inequality (LMI) form for using the convex optimization algorithm. Through the proposed design methods, the considered LPV system with external disturbance driven by the designed controller is passive and asymptotically stable subject to pole-assignment.
