摘要
为了克服传统方波无刷直流电机(BLDCM)控制存在起动抖动明显、转矩脉动大、噪声大等问题,文章提出了基于降阶卡尔曼滤波算法的无位置传感器矢量控制方法,利用空间电压矢量脉宽调制技术建立了无刷直流电机控制模型。在此基础上利用FPGA搭建了硬件控制系统,通过仿真软件MATLAB对系统进行了仿真和验证。实验结果表明系统具有良好的动静态性能,验证了数字硬件电路设计的正确性。
In order to overcome the problems of obvious starting jitter,large torque ripple and large noise in the traditional square wave brushless DC motor(BLDCM)control,a position sensorless vector control method based on reduced-order Kalman filter algorithm was proposed.The control model of brushless DC motor was established using space voltage vector pulse width modulation technology.On this basis,a hardware control system was built using FPGA,and the system was simulated and verified by the simulation software MATLAB.The experimental results showed that the system had good dynamic and static performance,which verified the correctness of the digital hardware circuit design.
