Design of Electromagnetic Car Based on PID Control Algorithm

本文介绍了以单片机MC9S12XS128为主控制模块,以L7805CV稳压模块、IR2104全桥驱动模块和SYN7318语音识别模块为主要硬件的智能小车的设计方法。我们通过LQ-1401M模块来采集路面信息,使用主控模块PID控制算法调节驱动电机的转速和转向以及舵机的角度,进而实现了智能小车的无线遥控、语音识别和自动循迹等各项功能。整个系统的电路结构简单,成本低廉,功能多样,可操作性高,适合学生学习及创新,通过测试该智能小车实现了预期的设计目标,各项指标达到系统要求。

This paper introduces the design method of the intelligent car based on MC9S12XS128 control module,L7805 CV voltage regulator module,IR2104 full bridge driver module and SYN7318 speech recognition medule. It uses LQ-1401 M module to collect the road information,and the main control module PID control algorithm is used to adjust the speed and steering of drive motor and the steering angle,so as to realize the wireless remote control,automatic speech recognition,tracking and other functions of smart car. The whole system has the advantages of simple structure,low cost,multiple functions,high operability,and is suitable for students to learn and innovate. Through the actual test,it realizes the expected design goals.
