基于MATLAB的倒立摆控制系统仿真

摘要

自动控制原理（包括经典部分和现代部分）是电气信息工程学院学生的一门必修专业基础课，课程中的一些概念相对比较抽象，如系统的稳定性、可控性、收敛速度和抗干扰能力等。倒立摆系统是一个典型的非线性、强耦合、多变量和不稳定系统，作为控制系统的被控对象，它是一个理想的教学实验设备，许多抽象的控制概念都能够经过倒立摆直观地表现出来。本文以一级倒立摆为被控对象，用经典控制理论设计控制器（PID控制器）的设计方法和用现代控制理论设计控制器（极点配置）的设计方法，经过MATLAB仿真软件的方法来实现。

ABSTRACT

Automatic control theory (including classical parts and modern parts) is a compulsory specialized fundamental course of the students majored in electrical engineering. Some of the curriculum concept is relatively abstract, such as the stability, controllability, convergence rate and the anti-interference ability of system. Inverted pendulum system is a typical nonlinear, strong coupling, multivariable and unstable system. It is an ideal teaching experimental equipment as a controlled object, by which many abstract control concepts can be came out directly. This paper chose first-order inverted pendulum as the controlled object. First, the PID controller was designed with classical control theory. Then pole-assignment method was discussed with modern control theory. At last, the effectness of the two methods was verified by MATLAB simulation software.

KEY WORDS: First-order inverted pendulum PID controller pole-assignment
