摘要 无刷直流电动机是本文介绍的一种双闭环调速仿真，用 PWM调制法对该系统的无刷直流电机的定子各相电路进行控制，从转自角度，对电流的检测反馈环节采用移相的方法在不同时刻得到转矩电流值；组合各个模块在一起构成系统仿真；利用示波器得到适合电动车利用的性能较好的电机转速曲线。 无刷直流电机的英文缩写为 BLDCM（Brushless DC Motor） ，由于它具有简单的构造、可靠的运行状态、较为低廉的成本、维护较为容易，所以有刷电机不会在机械换向时出现火花、发出噪音、也不会被无线电干扰，寿命也较长。同时保留了它高效、损耗少、易于调速的优点。 本文利用 MATLAB的仿真功能，研究了 BLDCM 的数学模型。研究BLDCM的数学模型从而得出这篇文章，仿真在 MATAB 软件中完成,模块库则是选择 SimulinkBlockset 中的，观察最后一个仿真，由此可知：良好的动、静态特性是电机具有的。 对于该论文，转速单闭环的 PI 调速控制系统是我们使用到的，转速抗干扰能力被显著的改善了，从此在无静差的情况下我们可以运行无刷电机了。历程从有刷电机发展而来、发展的状况在目前、发展的计划在未来是我们对无刷电机首先阐述的。结构组成在电机上被我们简洁明了的阐述了一下，工作原理对于电机被我们论述了一下，最后无刷直流电机的在工业和生产中在各个方面的使用情况也被我们大概学习和了解了一下，更多的几个电机中的模型也被我们举例举出，然后数学模型被构建起来，随即建模了每一个模块利用 matlab/simulink 软件，然后利用这些模块对这个系统进行仿真。 58576

Abstract In the paper,we introduced an electric vehicle with Brushless DC motor double closed loop speed control simulation, using PWM modulation method of the system without each circuit of the Brushless DC motor stator phase control, from the transfer from the point of view, on the current detection feedback link in the different times by the current moment value by means of phase shifting method; modules together to form a system simulation; using oscilloscope are suitable for electric vehicle use performance better motor speed curve. Brushless DC motor is an acronym for BLDCM (Brushless DC motor), because of its simple structure, reliable operation, low cost, easy to maintain, the brush motor effectively avoid the mechanical commutation spark, noise, radio interference and short service life of the shortcomings of. While preserving its efficiency, less waste, easy speed advantages. And firstly, we, in this paper the speed single loop PI speed control system is used to speed anti-interference ability was significantly improved, from the non static difference we can run brushless motor. Process from the brush motor development, development of the situation in the development plan in the future is the brushless motor. Structure of the motor is our clear and concise exposition about the working principle for the motor is we discuss about. Finally, the Brushless DC motor in industrial production in all aspects of the situation is we to learn about and understand a little more of several motor models We cite examples, and then the mathematical model is constructed, and then modeled each module using matlab/simulink software, and then use these modules to simulate the system.
