摘要: 研究一类时滞线性参数变化(LPV)系统的H控制问题,采用基于仿射参数的Lyapunov函数提出了稳定性能分析和控制器设计的充分条件.同时应用投影定理,借助附加矩阵解除了参数的Lyapunov函数矩阵与系统矩阵的耦合,得到以线性矩阵不等式(LMI)形式表示的条件.并且通过多凸技术把得到的无限维线性矩阵不等式转换为有限维线性矩阵不等式,从而使问题可以求解.数值仿真表明,性能得到满足同时也证明了方法的可行性.

Abstract: As for the H controller of a class of delay-time linear parameter varying systems(LPV),a series of sufficient condition for the analysis of performance and the existence of the controller is provided,which is established in terms of the affine parameter-dependent Lyapunov functions.Using the projection lemma and with the help of the some slack matrices,the parameter-dependent Lyapunov functions matrices and the system matrices are decoupled so that the condition of the linear matrix inequalities(LMIs) is given.In order to solve the infinite-dimensional LMIs because of the LPV,it is necessary to use the multiconvexity technique.A numerical example is used to show the feasibility of the proposed methods.
