该控制器输出部分的比例因子可以根据转矩的变化趋势经自适应机构的模糊规则库在线调整,不仅可以使永磁同步电机直接转矩控制系统保持恒定的开关频率,而且可以有效地减小磁链和转矩脉动,特别是低速时的转矩脉动。仿真验证了自适应模糊永磁同步电机直接转矩控制策略的有效性。

-The output of the controller part of the scale factor by the adaptive mechanism of the fuzzy rules according to the torque trend library online adjustments, not only can make a permanent magnet synchronous motor direct torque control system to maintain a constant switching frequency, and can effectively reduce theflux and torque ripple, especially at low speed torque ripple.The simulation results show the effectiveness of adaptive fuzzy permanent magnet synchronous motor direct torque control strategy.
