摘要
以ARM微控制器为控制核心,IR2104驱动的MOSFET全桥驱动电路和霍尔摇杆为平台,构建了大功率直流有刷电机的控制系统。结合脉宽调制技术的应用,设计了一套有效可行的电机控制算法。实验结果表明,系统控制起来简捷易行,算法设计上安全灵活人性化,并具有小角度大半径转弯、大角度小半径转弯和原地零半径转弯的性能。可直接应用于电动轮椅、电动车等领域。
Constructs a high-power DC brush motor control system,which takes ARM microcontroller as the control of the core,IR2104-driven MOSFET full-bridge driver circuit and Hall rocker as the platform.And we design a set of effective,feasible motor control algorithms,combined with the application of pulse width modulation technology.The results of the experiment show that the operation of the system is simple and easy,the design of algorithms is safe,flexible and humanized,and the system has the capabilities of turning at small-angle large radius,large-angle small radius and zero radius.The system can be directly applied to electric wheelchairs,electric cars and other fields.
