摘要
采用TMS320LF2812为主控制器并配以高速逻辑电路,以四相8/6极开关磁阻电动机为对象,设计了一种性能优良的开关磁阻电机速度控制系统。介绍了系统的结构和工作原理,给出了位置检测、电流检测、PWM输出及故障保护等电路设计,利用DSP的丰富外设资源,达到简化电路结构、提高运行可靠性的目的。
Based on 4 phase, and 8/6 pole switched reluctance motor （SRM）, a switched reluctance drive system was presented, which had excellent performance. It adopted TMS320LF2812 as main controlling unit associating with high speed logic unit, introduced controller＇s structure and each part principle of system in detail as well as the current detection, position sensing, PWM output and fault protection. The full use of the abundant peripheral resources of DSP achieved the aim of simplifying the circuit structure and improving the performance reliability.
