摘要
提出了一种新的内置式永磁同步电机弱磁调速的电流调节算法。该算法能够保证电机在整个弱磁调速区以最大的转矩电流比运行。其d轴电流根据外部转矩、转速给定和母线电压值的变化来决定,q轴电流分量则由d轴电流值和转速值来决定。文章通过系统仿真验证了该算法具有动态反应快、调速区间转换平稳的特性。
The paper preresents a novel current regulation algorithm for Interior permanent magnet synchronous motor that provides maxium torque-per-ampere capability in the entire fieldweakende region. The algorithm provides robust current regulation with manximum efficiency and torque capability for PMSM manchines despite significant in the voltage soure and machine parameters. The algorithm identifies when the current regulator statrts to saturate and detemines the optimum d-axis current connmand for the machine. The q-axis current command is determined from the torque command and d-axis xurrent feedback. Simulation results from a machine prototype show that the algorithm provides good overall dynamic response and smooth transitions into the field-weakened region with maximum torque-per-ampere capability.
