一种比例调节转速差的Arduino小车设计

An Arduino Car Design by Proportional Adjustable Speed Difference

针对小车运行中因路面摩擦、机械结构等外界因素影响,运动路线出现偏移的问题,提出了闭环调节车轮转速的设计方法。系统使用Arduino控制板采集左右车轮转速,经过比例调节计算后对一侧车轮驱动进行修正,小车能实现两侧车轮同速运行,结果表明:基于Arduino控制的车速采集与反馈调节系统开发灵活,成本低,对基于算法的运动控制系统研究有一定推广价值。

For the problem of the movement route offset which because of road friction,mechanical structure and other external factors during the car running, the design method of closed - loop wheel speed is proposed. The system uses Arduino to collect the left and right wheel speeds,after the proportional adjustment calculation, one side wheel drive is modified, car can achieve both sides of the wheel at the same speed,the results show that the speed acquisition and feedback control system based on Arduino control is flexible and the cost is low,It is of great value to study the motion control system based on algorithm.
