摘要
针对已有无刷控制器存在控制方式不灵活,通用性差等问题,设计并开发了可编程无刷电机控制实验系统.该实验系统提供了一种可重复开发方案,只需使用其配套的上位机编程软件,就能在控制信号与电机输出之间建立自由映射,直接驱动霍尔无刷电机.其系统硬件部分基于ARM(Advanced RISC Machine)-Cortex M3 MCU(Multipoint Control Unit),可同时支持数字电平、模拟信号以及脉冲宽度调制信号(PWM:Pulse Width Modulation);上位机软件基于PyQt5开发,主要包括引导窗界面与主窗口.测试电机可根据自定义控制信号与外界设备进行通信且可达到程序预期设计转速,该系统可为电机控制教学提供新的实验方案.
Abstract
In order to enrich the experimental content of the university experimental teaching platform,a programmable brushless motor control experimental system is developed.To address the problems of inflexible control mode and poor versatility in existing brushless controllers,the experimental system provides a repeatable development scheme,which can directly drive a Hall brushless motor by establishing a free mapping between control signals and motor outputs using its accompanying upper computer programming software.The hardware is based on ARM(Advanced RISC Machine)-Cortex M3 MCU(Multipoint Control Unit),which can support digital level,analog signal and PWM(Pulse Width Modulation)signal input at the same time.The upper computer software is developed based on PyQt5,including the guide window interface and the main window.After testing,the motor can communicate with external devices according to the customized control signal and can reach the expected design speed of the program,and the system can provide a new experimental solution for teaching of motor control.
