南京工程学院 本科毕业设计（论文） 题 目：电动汽车异步电机矢量控制研究 Graduation Design (Thesis) Study on the?control of electric vehicle?induction motor?vector By Wei Wang Supervised by Prof. Weijun Zhao Nanjing Institute of Technology June, 2015  摘 要 在日常生活中，在各种各样的领域电动机都被广泛的应用着，人们渐渐地早已离不开电动机。与之相对应的是越来越多的汽车被投入使用，但是传统汽车使用的内燃机在各个方面已经给人类带来了困扰，所以科学家们叫目光投入到用电动机去替代内燃机中去了。纯电动汽车由此应运而生。 纯电动汽车一般是使用异步电机作为驱动，控制电机的方式多种多样，此时本文采取矢量控制的方式。 本文主要实现了异步电动机的驱动电路的绘制和控制程序的编程。驱动电路的绘制是在protel 99 SE上完成的。而软件编程则是基于Keil的平台。本文采用STM32F103系列微处理器作为主控制器芯片，设计了以H桥模块、逆变电路模块为主要模块的异步电动机驱动电路，并通过编码器、霍尔电流传感器测量实际的电机运行参数得到反馈系数，编写了以矢量控制方式作为核心算法，电流控制的PWM电压源逆变位控制方式的转差型异步电动机矢量控制系统对三相交流电机进行控制。 关键词：电动汽车；异步电机；矢量控制；STM32 ABSTRACT In the daily life, in a wide variety of fields motor is widely used, people gradually can not get away from the motor.?With more and more cars are put into use, but using the traditional automobile internal combustion engine in all aspects has to human troubled, so scientists call eyes into the motor to replace internal combustion engine to.?Pure electric vehicles thus came into being. Pure electric vehicles generally use the induction motor as the drive, and control the way of the motor is varied, at this time this paper adopts the way of vector control.. In this paper, the main asynchronous motor drive circuit drawing and control program programming.?The drive circuit is drawn on the Protel 99 SE.?And software programming is based on the Keil platform.?The STM32F103 Series MCU as the main controller chip, the design of the H-bridge module, inverter module as the main module of the asynchronous motor drive circuit, and the encoder, the Hall current sensor measuring the actual operation parameters of the motor feedback coefficient, written in vector control as the core algorithm, current control PWM voltage source inverter bit control mode of slip type asynchronous motor vector control system for three-phase AC motor control.
