| 摘 要： | 为了控制无轴承永磁同步电机的旋转和转子的稳定悬浮,设计出了以TMS320LF2407A为微处理器核心的无轴承永磁同步电机控制系统,充分利用TMS320LF2407A的中断系统设计出能同时控制电机电磁转矩和径向力的软件模块,利用DSP的QEP模块和光电编码器的复位中断CAP6INT实现电机位置的准确检测.最后通过试验测试控制系统输出的转矩绕组和径向力绕组的指令电流波,验证了软件系统设计的实时性和准确性,证明其能满足无轴承永磁同步电机的旋转和稳定悬浮的要求.

| Abstract: | A control system which is based on TMS320LF2407A realizes to control rotation and stable suspension of bearingless permanent magnet-type motor.The software module is designed by interrupt system to control electromagnetic torque,the motor position angle is checked by QEP and CAP6INT.At last,the command current of the torque winding and radial force winding was tested.The results from software system prove that the system is able to meet the requirement of rotation and stable suspension of bearingless permanent magnet-type motor. |
