毕业设计中文摘要

切换系统是按某种切换规则在各子系统之间切换的混杂系统，是混杂系统理论与应用研究中非常活跃的一个分支。切换系统滑模控制问题是现代非线性系统控制中的一个重要课题，在过去的几十年中得到了广泛的关注，而且已被成功用于大量实际系统。这种控制策略与其他控制的不同之处在于系统的结构并不固定。它可以在动态过程中，根据系统当前的实时状态来对其进行控制，从而达到预定的控制目的。具有响应速度快，对参数摄动不敏感、鲁棒性能好等优点。许多实际系统本身具有切换的特性，例如含有继电、饱和、滞环等环节的被控对象以及工业上常见的多液罐系统。此类系统适宜用切换系统来进行建模分析，并设计相应的切换控制器来对其进行控制。

Title The design of sliding mode control about switched systems Abstract

Switched systems form a class of hybrid systems consisting of a family of subsystems with a rule specifying the switching among them. It’s a very active branch of research on the theory and application of hybrid systems. The issue of sliding mode control about switched systems is a very important issue among modern nonlinear systems control theory, which have received increasing attentions in the past few years. It has been used in a large number of practical systems successfully. Its control strategy is different from other systems for it has a system with a unstable structure .It can control the system according to the Real-time status of the system in the dynamic process so as to achieve the expected result. It has the advantages of fast response, being insensitive to parameter perturbation, having good robustness and so on. Many practical systems have the characteristic of switching such as the controlled device with the links of relay, saturation, hysteresis and the liquid fillings systems which is familiar in the factory. The systems mentioned above which is modeling by using the switch system and using the corresponding controller can work very well.

This paper mainly divided into four chapters by learning the basic theory of the sliding mode control about switched systems and the knowledge of the Simulink software: The first chapter introduces the basic development process of sliding mode control about switched system; The second chapter introduces the basic theory of sliding mode control about switched system; The third chapter introduces how to design the observer of switched systems, and gives the simulation of concrete example simulation by Simulink software; The fourth chapter introduces how to carry on the sliding mode control design of simple switched systems, and also gives the simulation of concrete example simulation by Simulink software, simulation curves is obtained, the performance of the controller is verified, the controller design of switched systems is accomplished.
