摘要
在分析无刷直流电动机数学模型及换相过程的基础上,在S imu link中,建立了无刷直流电动机系统的模型。其中,重点采用开关函数对逆变器进行了建模,加快模型仿真速度。同时该模型可以实现电机性能、故障保护、以及PID速度闭环控制的综合仿真。仿真实验结果表明,该模型对电流的动态模拟准确,计算效率高,为无刷直流电动机系统仿真提供了一种新方法。
Based on the analysis of the mathematical model and commutation of the Brushless DC motor ( BLDCM), the simulation model of the BLDCM system was proposed in Simulink. The inverter model was built based on switching function to accelerate the simulation speed. All the simulation of motor performance, fault protection, PID speed loop control system can be achieved. Simulation results show this model has the advantage of high accuracy current dynamic simulation and high calculation efficiency. This offers a new method for the BLDCM system simulation.
