北方民族大学 学士学位论文 题目: 直流电机PWM调速系统的DSP实现  摘 要 随着科学技术的不断发展，电力电子技术和计算机的不断进步，以前老的电机调速技术再也不能满足人们的需求，进步已变得不可阻挡。所以，经过一代又一代人的努力，直流电机调速已经向着全面数字化的方向发展了，而脉宽调制技术（PWM）正是控制数字化的基础之所在。近几年来，数字信号处理器（DSP）集成的硬件资源愈加丰富，直流电机调速以DSP实现受到了广泛的关注和应用，然而对于DSP在这方面的应用实至名归，它在许多领域都得到了极大地使用，诸如电气、航天、通讯、医药卫生和电子等方面都有极广的使用。 本文首先提出了直流电机PWM调速的控制要求，对传统方法进行了列举；然后系统地阐述了该文使用系统的组成及其数字化控制原理，从整个调速系统的关键技术角度分析了计算机与DSP相结合的直流电机PWM调速的实现；最后详细描述了系统的软件设计，设计过程运用了模块化设计。 本文使用了TMS320F2812DSP，它在C2000系列中非常的突出，对它的深入学习是学习DSP原理的理想的入门芯片。本文对该芯片有非常详细的介绍，这也对我以后的学习帮助很大。 关键字：直流电机、PWM、调速、DSP  Abstract With the development of science and technology, progress of power electronic technology and computer technology, before the motor speed old cant satisfy peoples needs, progress has already become the irresistible. So, generation after generation of peoples efforts, the DC motor speed control has become a comprehensive digital direction, while the pulse width modulation (PWM) is the foundation of digital control of. In recent years, digital signal processor (DSP) hardware resources more integrated abundance, DC motor speed regulation is realized by DSP received extensive attention and application, however, for the application of its DSP in this regard, in many areas have been greatly used, such as electrical, aerospace, communications, medical and electronic and so on have the use of a wide range of. This paper first proposed to control the executives and the DC motor, the traditional methods are listed; and then systematically expounded the composition and principle of the digital control system, analyses the implementation of PWM DC motor speed control computer and DSP combined from the key technology point of the speed regulation system; finally, a detailed description of the software design system software design, which directly affects the implementation of system design, so careless. The system software design uses the modular design, but a module is absolutely independent, so it is very convenient for adjus
