摘要

本文主要研究的是一级倒立摆的控制问题，并对其参数进行了优化。倒立摆是典型的快速、多变量、非线性、强耦合、自然不稳定系统。由于在实际中有很多这样的系统，因此对它的研究在理论上和方法论上均有深远的意义。本文首先简单的介绍了一下倒立摆以及倒立摆的控制方法，并对其参数优化算法做了分类介绍。然后，介绍了本文选用的优化参数的状态空间极点的配置和PID控制。接着建立了一级倒立摆的数学模型，并求出其状态空间描述。本文着重讲述的是利用状态空间中极点配置实现方法。最后，用Simulink对系统进行了仿真，得出在实际控制中是两种比较好的控制方法。

Abstract

This paper mainly studies the level of the inverted pendulum control problem, and its parameters are optimized.Inverted pendulum is a typical rapid, multi-variable, nonlinear, strong coupling, natural unstable system.In practice, however, because there are a lot of such a system, so the study of it in theory and methodology have profound significance.This article first introduced the inverted pendulum, and simple of the inverted pendulum control method, made a classification and the parameter optimization algorithm is introduced.And then, introduced in this paper, choose the optimization of the parameters of state space pole configuration and PID control.Then set up the level of the mathematical model of inverted pendulum, and find out the state space description.This paper focuses on the pole assignment method is the use of state space.Finally, the system are simulated using Simulink, it is concluded that in the actual control is two good control method.This paper mainly studies the level of the inverted pendulum control problem, and its parameters are optimized.Inverted pendulum is a typical rapid, multi-variable, nonlinear, strong coupling, natural unstable system.In practice, however, because there are a lot of such a system, so the study of it in theory and methodology have profound significance.This article first introduced the inverted pendulum, and simple of the inverted pendulum control method, made a classification and the parameter optimization algorithm is introduced.And then, introduced in this paper, choose the optimization of the parameters of state space pole configuration and PID control.Then set up the level of the mathematical model of inverted pendulum, and find out the state space description.This paper focuses on the pole assignment method is the use of state
