本论文中,以一级倒立摆为研究对象,对它的起摆以及稳定控制做了研究，主要研究工作如下: 1.首先介绍了倒立摆系统的组成和控制原理,建立了一级倒立摆的数学模型,对倒立摆系统进行定性分析,但在平衡点是能控的、能观的。 2.分析了倒立摆的起摆过程,对倒立摆的起摆能量反馈控制进行分析与说明。 3.在matlab2014a的simulink库下对倒立摆构造单级倒立摆状态反馈控制系统的仿真模型和构造具有状态观测器的单级倒立摆状态反馈控制系统的仿真模型。 4.对这次仿真的总结。(In this paper, in order inverted pendulum for the study, since it swing and stability control to do the research, the main research work is as follows: 1. The first introduces the composition and control principle of inverted pendulum system, the establishment of inverted pendulum The mathematical model of inverted pendulum system for qualitative analysis, but at the equilibrium point is controllable, and can view. 2. Analysis of the inverted pendulum swing the process of inverted pendulum swing the feedback control of the energy analysis and explanation. 3. Under matlab2014a the simulink library to construct a single-stage inverted pendulum swing state feedback control system simulation model and the structure has a state observer status feedback single-stage inverted pendulum control system simulation model. 4. Summary of the simulation.)
