摘要由于计算机网络技术的日新月异,与此同时我们在生活中对于网络控制技术的需求越来越高。网络控制系统,因其具有低廉的造价、分布的控制等优点,而广泛地应用于电力、电子和宇航等远程控制系统中。目前,越来越多的专业人士投身于非线性网络系统的建设里。之前因为更多人研究线性网络控制系统,所以对于非线性网络控制系统领域,我们目前还需要更多的探寻。
现在非线性网络控制系统中存在很多的问题,像是网络诱导时延问题、数据包丢失问题、单包传输与多包传输问题、数据包的时序错乱问题、网络调度问题,时钟同步问题,还有系统的稳定性问题等等。因此,在非线性网络控制领域,还需要付出很多努力。86197
本文主要研究了非线性网络控制系统这一领域,考虑了非线性网络控制系统的输出反馈控制器设计问题。 对于非线性网络控制系统建模,我们是在考虑采样器到控制器的时延和控制器到执行器的时延的基础上。首先对系统进行数学建模,然后利用Matlab软件和线性矩阵不等式技巧,我们可以对该非线性网络系统稳定性进行分析。对系统稳定性进行分析后,能够得出了控制器存在所期望的条件,我们就可以按照这个条件对控制器进行设计。

Abstract
Due to the rapid development of computer network technology, at the same time, we need more and more network control technology in our daily life。Network control system, because of its low cost, distributed control and other advantages, and widely used in electric power, electronic and aerospace and other remote control system。At present, more and more professionals are engaged in the construction of nonlinear network system。Because more people to study the linear network control system, so the field of nonlinear network control systems, we need to explore more。
Now nonlinear networked control system has many problems, like network induced delay, data packet loss, single packet transmission and multi packet transmission, data packet timing disorder, network scheduling, clock synchronization and system stability problem and so on。Therefore, in the field of nonlinear network control, but also need to pay a lot of efforts。
In this paper, we mainly study the nonlinear network control system, considering the output feedback controller design problem of nonlinear network control system。For the nonlinear networked control system is modeled, we are considering the sampler to the controller delay and controller to the implementation of the delay based。At first, the mathematical model of the system is modeled, and then using Matlab software and linear matrix inequality technique, we can analyze the stability of the nonlinear network system。After analyzing the stability of the system, we can get the condition of the existence of the controller。 We can design the controller according to the condition。
