摘要
在传统智能小车驱动电路设计中,较多考虑使用直流电机还是步进电机,电机功率、能耗等性能参数。使用具有arm Cortex M4内核的STM32嵌入式平台控制四轮的4个直流电机。文章基于PWM技术及PID算法,对四轮进行精准地速度、转向及启停控制,实验表明此小车具有优越各种地形适应能力。
In the traditional intelligent car drive circuit design,DC motor or stepping motor,motor power,energy consumption and other performance parameters are considered.The four DC motors with four wheels are controlled by STM32 embedded platform with arm Cortex M4 kernel.Based on the PWM technology and PID algorithm,the accurate ground speed,steering,and start-stop control of the four wheels are carried out.The experiment shows that the vehicle has the superior adaptability to all kinds of terrains.
