Abstract

In this study, it is aimed to design a rotor-oriented sensorless direct vector control for the speed control of an induction motor (IM). For this purpose, all the states required for direct vector control in addition to the step-shaped load torque and rotor resistance are estimated using extended Kalman Filter (EKF). Simulation results demonstrate a good performance and robustness to variations of load and rotor resistance.
基于扩展卡尔曼滤波的感应电机无传感器直接矢量控制
本研究的目的是设计一种面向转子的无传感器直接矢量控制,用于感应电机的速度控制。为此,利用扩展卡尔曼滤波(EKF)估计直接矢量控制所需的所有状态以及阶跃负载转矩和转子电阻。仿真结果表明,该方法具有良好的性能和对负载和转子电阻变化的鲁棒性。
