本文针对以上问题，运用理论研究与实证分析、静态分析与动态分析相结合等研究方法，从乡镇政府与村民委员会关系、村"两委"关系以及村"两委"与村民关系等三方面入手，系统地分析了农业税费改革对村民自治的影响，认为农业税费改革将有利于减弱村民委员会的"行政化"、理顺村"两委"与群众的关系、缓解村"两委"矛盾、促进村"两委"的组织建设，同时也为村民自治带来了一系列问题，如财政问题、税费尾欠问题等，最后提出应从基层政权改革、干群关系、两委关系以及农村集体经济等四个方面来推进后农业税时代的村民自治。

Based on structural singular value theory, the robust control model for vibration response is built, and the design method of μ- synthesis controller is presented. The main ideal is as follows: by introducing fictive uncertainty, the robust performance problem of vibration response is transformed into the robust stability problem of the augmented system. It can be solved by D K iteration.

基于鲁棒结构奇异值理论，建立了振动响应的鲁棒控制模型，提出了设计鲁棒μ控制器的方法，通过引入虚构的不确定块，将振动系统响应性能的问题转化为广义系统的稳定鲁棒性问题求解，兼顾了系统的稳定鲁棒性和性能鲁棒性。
