电动汽车电机控制器软件设计

摘要：在目前全球能源危机和温室效应越来越严重的情况下，电动车以其无污染、低噪声、效率高，便于操作等优点，越来越受到人们的青睐。电动汽车的核心是电动机，电动机中最具优势的是无刷直流电动机，而无刷直流电机的控制是电动机的关键技术。本课题运用CYPRESS公司的CY8C24533型芯片，在控制器硬件设计的基础上，进行了系统控制软件的设计。

本文首先分析研究了车用电动机的发展动态，阐述了无刷直流电动机的优势所在。之后针对无刷直流电动机，详细地介绍了它的工作原理、数学模型、驱动性等相关知识。然后立足它的工作原理等知识，我对无刷直流电动机的控制器进行了大体设计，并对其关键部分如PWM、ADC进行了详细的探究；并在前文的基础上，利用了手头的资料，使用C语言对无刷直流电机控制器的软件进行编写，取得了一定的成果。

Software Design of

the Electric Vehicle Motor Controller

Abstract: In the case that current global energy is in a crisis and the greenhouse effect becomes more severe, the electric car with its no-pollution, low noise,

high-efficiency, easy operation and so on,is being more and more popular in

people. The core of electric vehicle is motor, and the brushless DC motor is

the most advantage of electric motor.And the brushless DC motor control

technology is the key technology of the electric motor.My issue has done a

software design of the controller of brushless DC motor on the base of its

hardware design with a chip named CY8C24533 designed by Cypress

Co.Ltd.

This paper analyzed the development of motor used on vehicle, describing

the advantages of brushless DC motor.And for brushless DC motor, this

article described a detailed presentation of its working principle,

mathematical model, driven-characteristics and so on. Then based on the

knowledge of how it works, I did a generally design with the brushless DC

motor controller,and did a detailed research of its key part like PWM、ADC

and so on;and beyond all of this above, I used C language to write a

software to control the brushless DC motor controller with some documents

by my hand,and I got a success.
