摘 要

直线一级倒立摆由直线运动模块和一级摆体组件组成，是最常见的倒立摆之一。设计直线一级倒立摆前,首先要应清楚直线一级倒立摆的定义及它的特性,其次用数学建模的方法建立直线一级倒立摆模型。再次PID控制器的结构与参数设计，将直线一级倒立摆当作简单的单输入单输出系统（忽略了小车位移的控制），采用了 PID控制器设计方法进行了控制器结构设计和参数设计。确定PID控制器主要参数KP、KI、KD,通过改变这三个参数的值,使直线一级倒立摆由开环不稳定系统变为闭环稳定系统。直线一级倒立摆系统在PID控制器下用MATLAB进行仿真,通过改变控制器PID主要参数,使得仿真曲线更接近理论曲线。这些便是直线一级倒立摆系统的PID控制算法设计的主要内容。

ABSTRACT

Inverted pendulum linear 1-stage stands upside down suspends is composed by the translation module and the level pendulum mass module, is most common stands upside down suspends one Front the design straight line level stands upside down suspends, first must be supposed the clear straight line level to stand upside down the definition and its characteristic which suspends, next stands upside down with mathematics modelling method establishment straight line level suspends the model. Once more the PID controller structure and the parameter design, stood upside down Inverted pendulum linear 1-stage suspends the regard simple single input list output system (to neglect car displacement control), used the PID controller design method to carry on the controller structural design and the parameter design. Determined PID controller main parameter KP, KI, KD, through change these three parameters the value, causes the straight line level to stand upside down suspends becomes the closed loop stable system by the split-ring unstable system. Inverted pendulum linear 1-stage stands upside down suspends the system to carry on the simulation under the PID controller with MATLAB, through the change controller PID main parameter, causes the simulation curve closer theoretical curve.These then are the straight line level stands upside down suspends the system the PID control algorithm design primary coverage.
