针对无刷直流电机的转矩脉动，采用电流滞环控制来抑制脉动；在Matlab/Simulink环境下，基于直流无刷电机的数学模型、转速和电流双闭环控制策略来建立无刷直流电机电流滞环控制系统的各个独立模块如BLDC本体模块、速度控制模块、电流滞环模块、逆变电路模块、脉冲信号模块等，再进行各功能模块的连接，搭建无刷直流电机的控制系统仿真模型，并在给定参数下进行仿真分析。%The current hysteresis loop tracking control is used to prevent the brushless DC motor from torque rippling. In the Matlab/Simulink environment, the independent modules of the brushless DC motor system the with current hysteresis loop tracking control are built based on its mathematical model and the speed and current double closed loop control strategy, such as BLDC ontology, speed control, current hysteresis, inverter circuit and pulse signal modules, which are connected to each function module to build a brushless dc motor control system simulation model and set up the paramters to do the simulation analysis.
