球杆系统控制器设计论文及matlab仿真毕业论文.doc

摘 要 以球杆系统作为主体，系统中的小球作为被控对象，设计一个模糊控制器，控制小球在装置导轨上的运行状态，分析小球在导轨上的运行状态，以此来反映模糊控制器的控制性能。设计首先对球杆系统组成结构及其基本原理进行分析之后，建立一个相对简化后的球杆系统模型；运用相关的模糊控制原理，建立球杆系统模糊控制规则，再对球杆系统进行模糊控制器设计。并在MATLAB仿真环境下建立控制器的仿真模型，对球杆系统进行仿真，测试模糊控制器的控制性能。 针对球杆系统自身存在的不稳定特性，在进行仿真时加入闭环反馈控制环节，这样不但可以提高系统的稳定性，还可以提高控制的精度，相较于其他一般控制，它更具有独特优势，更符合人类思维。 球杆系统作为如今研究控制理论的经典案例，与模糊控制融合之后，能更好地表现模糊控制在自动控制方面的优良特性。 关键词：球杆系统；模糊控制；MATLAB建模  ABSTRACT In the ball and beam system as the main body, the ball as a controlled object,design a fuzzy controller , to control the ball in the guide rail device running status. Analysis the ball movement on the guide rail, in order to reflect the fuzzy controller performance. First，the design analysis the composition structure and the basic principle of the ball and beam system , then establish a relatively simplified of the ball and beam system model; using the principle of fuzzy control, to establish fuzzy control rules of the ball and beam system, design a fuzzy controller to the ball and beam system. And in the MATLAB simulation environment, establish the simulation model of the controller, simulate the club system and test the control performance of the fuzzy controller. For the ball and beam system own existence the instability characteristics, in the simulation by adding closed loop feedback control link, which can not only improve the system stability, but also can improve the control accuracy, compared with other general control, it is more unique advantages, more in line with human thinking. Club system as a classic case in study control theory, and after fusion with fuzzy control, can performance the excellent characteristics of fuzzy control in the automatic control . Key words: the ball and beam system；fuzzy control；MATLAB modeling 目 录 1 绪论………………………………………………………………………………1 1.1 课题背景和研究意义…………………………………………………… 1 1.1.1 课题背景…………………………………………………………1 1.1.2 课题的研究意义…………………………………………………1 1.2 模糊控制的发展及研究状况…………………………………………… 2 1.2.1 模糊控制论的产生与发展……………………
