在傳統(tǒng)智能小車驅(qū)動電路設(shè)計中,較多考慮使用直流電機還是步進(jìn)電機,電機功率、能耗等性能參數(shù)。使用具有armCortexM4內(nèi)核的STM32嵌入式平臺控制四輪的4個直流電機。文章基于PWM技術(shù)及PID算法,對四輪進(jìn)行精準(zhǔn)地速度、轉(zhuǎn)向及啟停控制,實驗表明此小車具有優(yōu)越各種地形適應(yīng)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.
