摘要
基于DSP丰富的片内外设资源,以电动机数字化控制系统为应用平台,介绍了当前常用永磁无刷直流电动机数字化控制系统,特别提出了运用键盘作为外部中断实现永磁无刷直流电动机的换向和速度控制独立运行的一种方案,并通过集成环境调试及实际样机实验,验证了此控制方案的可行性,实现了基于TMS320LF2812的永磁无刷直流电机闭环转向与速度控制。
On the base of the rich resources of DSP- chip peripherals and the platform of digital controlling motors, investigated the current common permanent magnet brushless DC motor digital controlling system, then especially advanced the use of keyboard as an external disruption to achieve permanent magnet BLDCM to control the velocity and the direction of rotation independently. By the integrating prototype test and debug environment, it verified the feasibility of this controlling program, achieving the closed-loop speed and direction control of BLDCM based on TMS320LF2812.
