本科毕业设计题目两轮自平衡小车研究学院电子信息工程学院专业自动化学生姓名刘长根学号 200910311332 年级 2009级指导教师罗浚溢职称博士年月日两轮自平衡小车研究专业：自动化学号：200910311332学生：刘长根指导教师：罗浚溢摘要：现在两轮自平衡小车的研究在全世界得到很大的关注。

本论文主要工作是对两轮自平衡小车的原理进行研究并且和提出一种设计方案。

本次设计方案是采用ENC-03MB陀螺仪传感器和MMA7361LC 三轴加速度倾角传感器构成小车的状态检测装置，使用算法使陀螺仪数据和加速度计数据的融合得到小车的倾角，再通过一定的算法使小车保持直立状态。

系统采用飞思卡尔公司的DSC 16位处理器XS128单片机为核心控制处理器，完成传感器信号的处理，滤波算法的实现和车身控制等一些任务。

在小车制作完成后，各个模块之间能够正常并且协调的工作，小车可以只无人干预的条件下实现自主平衡，运用手机蓝牙可以控制小车的前进、后退、左右转动等各个动作。
