摘要

本文介绍了用模糊速度控制器对并联的两台异步电动机进行无速度传感器矢量控制的特点。用自然观测器估计了并联异步电动机的转速。采用模糊速度控制器可以减小负载不平衡条件下两台异步电动机的转速差和转矩脉动。给出了仿真结果，并与现有的PI控制器进行了比较。模糊速度控制器在负载不平衡情况下表现出良好的动态性能。

Speed-sensorless vector control of parallel connected induction motor drive with fuzzy controller

This paper presents the characteristics of a speed-sensorless vector control of two induction motors connected in parallel and fed by a single inverter with fuzzy speed controller. Speeds of parallel connected induction motor drives are estimated by natural observer. The speed difference between two induction motors and the torque ripple are reduced under unbalanced load conditions when fuzzy speed controllers are used. Simulation results are presented and are compared with the existing well known PI controller. Fuzzy speed controller shows a good dynamic performance under unbalanced load conditions.
