查询词典 surveys

The incomparability comes from two sources: the first is the problem of statistic system. The income data in China are distinct surveys, using different questionnaires and administered by different units within National Bureau of Statistics. The second is the problem of China's economic structure. China's current dual economic structure determines the disparity between rural and urban residents.

所谓"不可比性"主要包括两层含义；首先是统计数据本身的问题，国家统计机关公布的居民收入分配数据分为"城镇居民"和"乡村居民"两部分，在统计口径、数据结构和公布形式上都存在差异；其次是城乡二元结构体制的存在所决定的不可比性，即中国目前的城乡二元结构体制造成了城、乡居民经济生活形态的差异，同等"收入"为城、乡居民带来的购买能力、生活质量和财富水平并不相等。

At first, this paper surveys nonlinear control and the applications of neural networks in control respectively. Then it studies definitions, mathematical descriptions and conditions of invertibility for nonlinear systems, which are used to analyze the feasibility of inverse system control method. Conclusions about the feasibility of inverse control and the realizability of αth-order inverse systems in engineering are achieved. Furthermore, this paper discusses the feasibility, structure and identification of neural network αth-order inverse system for general single-input single-output continuous or discrete nonlinear systems and various composite control methods based on the αth-order inverse. At last, as a part work of an actual project, this paper focuses on the design of neural network αth-order inverse control method for thyristor controlled series compensation in power systems and its effect in improving the stability of power systems.

本文首先分别概述非线性系统的控制与人工神经网络在控制中的应用；然后研究非线性系统各种可逆性的定义、数学描述及可逆性条件，并用于分析逆系统控制方法的可行性，得出有关逆系统控制方法可行性的结论，阐明一般情况下α阶逆系统才工程可实现；接着本文针对一般单输入单输出连续、离散非线性系统，研究神经网络α阶逆系统的可行性、结构与辨识以及基于神经网络α阶逆系统的各种复合控制方法，并给出应用例子；最后本文结合实际项目，针对采用可控串补的电力系统，设计神经网络α阶逆系统控制方法，研究其对提高电力系统稳定性的作用。
