无轴承开关磁阻电机的减振控制策略

Vibration Control Strategy for Bearingless Switched Reluctance Motors

  • 摘要: 脉动的径向电磁力导致的定子振动问题阻碍了磁阻电机的推广应用。该文研究了一种利于减小无轴承开关磁阻电机(bearingless switched reluctance motor,BSRM)定子电磁振动的悬浮运行控制策略。该控制策略在保证电机转子悬浮所需悬浮力一定的前提下,以减小定子极受到的径向电磁力为控制依据。基于悬浮运行原理和数学模型,叙述了减振控制策略的基本原理;推导了主绕组电流、悬浮绕组电流、开通关断角等电机相关控制参数的计算方法;并给出了系统控制框图。仿真和实验结果均证实了新的控制策略不仅能实现电机的稳定悬浮旋转运行,同时有利于减小BSRM定子电磁振动,验证了理论分析的正确性和可行性。

     

    Abstract: The problem of serious vibration caused by magnetic radial force ripple acting on the stator pole has become a major obstacle encountered in the application of reluctance motors. A control strategy is proposed to reduce the stator electromagnetic vibration for the bearingless switched reluctance motor(BSRM). Under the premises of certain suspension force for stable levitation of the rotor, the control basis of this scheme is to reduce the stator radial force. Based on its operation principle and mathematical models, this paper introduced the fundamental control method for decreasing stator vibration; deduced the motor control parameters such as the main winding current, suspension winding current, turn-on angle and turn-off angle. In addition, a block diagram for this vibration control strategy is developed for its implementation. Simulation and experimental results show that the control strategy not only realizes stable suspension operation for the motor, but also decreases stator vibration, thus validating rightness and feasibility of the theory.
