摘要
本文采用飞思卡尔16位单片机MC9S12DG128为核心,辅以直流电机驱动、LCD显示、加速度传感器MXD2020M、光电传感器数据采集等电路组成,实现了电动车通过黑线引导驶上跷跷板并在板上能自行调节平衡。电机控制采用了PID的控制算法,有效的减小超调量和静态误差,缩短调节时间。该模型在当代汽车行业中具有一定的实用性。
In this article,using Freescale＇s MCU-MC9S12DG128,complementary with dc motor drive,LCD display,acceleration sensor MXD2020M,photoelectric sensor data collection,realized the electric circuit by the black line up to guide the seesaw and this electric car could adjust themselves balance on boards.Motor control adopted PID control algorithm that could be the decrease of the effective overshoot and static error,shorten the regulating time.This model has practical value in the car industry in contemporary.
