基于FPGA的无位置无刷直流电机控制系统设计

The Design of Sensorless BLDCM Control System Based on FPGA

根据反电动势过零检测算法,利用FPGA的硬件逻辑资源,构建了一种无位置无刷直流电机实时控制系统,并且详细阐述了单神经元自适应PSD在电流环调节上的应用。试验结果验证了系统的可行性,具有良好的动态性能和鲁棒性。

According to the back-EMF method and the using of FPGA＇s hardware logic resources,this paper build a sensorless brushless DC motor（BLDCM） real-time control system,and controlling method of current loop with single neuron adaptive PSD controller is discussed in detail.With good dynamic performance and robustness,the results demonstrate the feasibility of the control system.
