摘　　要：在详细分析无刷直流电机(BLDC)数学模型的基础上,提出并设计无刷直流电机系统转速、电流双环控制策略。首先,在Matlab/Simulink中,分别使用已有模型,调用由Matlab语言编写的m函数及S函数构建模型3种方法,建立各子功能模块,并在此基础上根据控制系统原理建立无刷直流电机系统仿真模型。通过仿真与试验,验证该控制策略的正确性与有效性。Based on the detailed analysis of Brushless DC motor （BLDC） model, a new dual-loop control method for BLDC control system is proposed and designed. In Matlab/Simulink, the isolated functional blocks, such as BLDC block, Speed controller block, Hysteresis current controller block, Inverter block ect, have been modeled. At last, the simulation model of a brushless DC motor control system is established and simulated. The simulation results have verified the correctness and effectiveness of proposed BLDC control strategy. This new scheme is also suitable for verifying the reasonability of other control algorithms and offers a new thinking for designing and debugging the actual motors.
