摘要
根据微步控制理论,设计了基于DSP的四相开关磁阻电机的驱动控制系统。本文首先对功率变换器及其驱动、电流检测、位置检测和系统电源等硬件电路进行设计,最后搭建以TMS320LF2407为控制核心的开关磁阻电机控制系统。实验表明这种控制策略控制简单,能够在低速下有效地抑制开关磁阻电机的转矩脉动。
According to the micro-step control theory,a switched reluctance motor drives based on DSP is designed. In this paper,the independent hardware circuits such as power converter and its drive,current detection,position detection and power supply source have been designed firstly. Then the switched reluctance motor drives taking the TMS320 LF2407 as the control core is established. Experiment results show that this strategy can effectively minimize the torque ripple and easy to be realized.
