基于空间矢量算法的双电机高可靠大功率伺服机构研究

摘要

在永磁同步电机的空间矢量控制原理的基础上,阐述了一种双电机大功率伺服系统的控制算法及其实现;采用Simulink建立双电机控制的电流、速度、位置的三闭环模型,并利用2台1.5kW级别的样机进行试验.试验结果证明,该控制算法的正确、有效.%In this paper, the algorithm and achievement of a double-motor high-power servo system control are introduced, which are based on the Space vector control of permanent magnet synchronous motor. Using the Simulink simulation software, three closed-loop model of double-motor control including electricity, velocity and displacement is established. By the experiment with two 1.5 kW photos, results show the control algorithm is correct and effective.
