Study of BLDC Motor Dual-loop Control Simulation

为了便于对无刷直流电机的运行特性和控制策略的研究,文章详细的介绍了无刷直流电机工作原理和数学模型,提出无刷直流电机的控制策略,采用电流环为内环,速度环为外环的双闭环控制,并根据数学模型搭建了Matlab/Simulink仿真模型进行仿真实验验证。仿真结果表明,整个系统运行平稳,具有良好的静、动态特性,从而验证了所提出的控制策略的正确性和有效性。

In order to facilitate the study of operating characteristics and control strategy of BLDCM, this paper detailed introduces working principle and mathematical model of BLDCM, designed a BLDCM control strategy, using the speed of the outer loop, current loop double loop control scheme of the inner ring, and built a mathematical model based on Matlab / Simulink simulation model for verification. The simulation results show that the closed-loop system is running smoothly and has good dynamic and static characteristics, thus verified the correctness and effectiveness of the proposed control method.
