摘要
无位置传感器控制方案是目前无刷直流电机控制的研究热点。论文给出了一种利用扩展卡尔曼滤波器(EKF)估计无刷直流电机转子位置和转速的方法,该方法仅需三相定子相电流即可实现对电机转子状态的估计,计算量小,成本低。针对提出的控制策略,文章在Matlab/Sim-ulink下进行了仿真。仿真结果进一步说明所提出的控制策略的有效性。
Sensorless control of brushless direct current motors（BLDCM） has become an active research field. This paper presents a method for estimating the rotor position and velocity of BLDCM using an Extended Kalman Filter（EKF）, phase current of three phase stator winding is the only signal needed for this method. The amount of computation for control system is reduced such that the method is suitable for low cost systems. The proposed method was simulated in Matlab/Simulink , and the result of simulation shows the effectiveness of the control strategy.
