在分析无刷直流电机 BLDC 数学模型的基础上 提出了无刷直流电机系统仿真建模的新方法 在 Matlab/Simulink中 建立独立的功能模块 如 BLDC 本体模块 电流滞环控制模块

速度控制模块等 再进行功能模块的有机整合 搭建无刷直流电机系统的仿真模型 为保证仿真

快速性和有效性 模型采用分段线性法生成梯形波反电动势 系统采用双闭环控制 速度环采用

PI 控制 电流环采用滞环电流控制 仿真结果证明了该方法的有效性 同时也适用于验证其他控制算法的合理性 为实际电机控制系统的设计和调试提供了新的思路-BLDC brushless DC motor based on the mathematical model of the proposed new method for the analysis of brushless DC motor system simulation modeling to establish independent functional modules in Matlab/Simulink module in the body, such as hysteresis current BLDC control module speed control module then organic integration of functional modules to build simulation models of brushless DC motor system in order to ensure rapid and effective simulation model using a piecewise linear method generates trapezoidal back EMF system uses a double-loop speed control loop with PI current loop control using hysteresis current control The simulation results show the effectiveness of this method is also applicable to other control algorithms to verify the reasonableness of the actual motor control system design and commissioning of new ideas
