摘要
在分析无刷直流电机(BLDCM)数学模型基础上,提出一种建立BLDCM双闭环调速系统的仿真建模新方法,转速环采用模糊PI控制器,电流环采用滞环控制器。在Matlab/Simulink环境下,将独立功能模块和S函数相结合,搭建各功能子模块,再进行有机整合,建立BLDCM调速系统的仿真模型。仿真试验结果表明系统响应速度快,控制精度高,运行稳定。
Based on the mathematical model of Brushless DC Motor(BLDCM),a novel method for modeling and simulation of BLDCM dual-loop control system was proposed with Fuzzy PI speed controller and Hysteresis current controller.In Matlab/Simulink,control subsystem blocks were modeled by the combination of isolated function blocks and S-Functions.The model of BLDCM can be established by the organic combination of the subsystem blocks.The simulation results verifed that the system has advantage of fast response speed,high control accuracy,and stable operation.
