基于DSP电机控制技术的研究 摘要 电机在各种电气传动和位置伺服系统中占有及其重要的位置，电机控制的目标主要是速度控制和位置控制。近年来，随着电力电子技术、微电子技术、材料技术的飞速发展，电机控制的研究也越来越重要，高性能电机控制系统也在不断地更新。尤其是将DSP技术运用到电机控制之后硬件的统一性与软件的灵活性可以有机结合，电机的数字化及集成化控制成了电机控制的发展方向。本课题以曾经在实际工程项目中使用到的步进电机为例，在实现这种电机的DSP控制的基础上，建立电机控制机平台，设计电机控制系统。 论文首先分析了电机控制的发展现状，指出电机控制的一般问题及DSP控制系统的特点。阐述了步进电机的基本构成、工作原理、控制系统的构成及其基本控制策略，给出了基于DSP的电机控制系统设计方案, 然后在前期的工作及所取得的阶段性成果的基础上，以TI公司的DSP TMS320C55为核心设计了硬件系统，并编写了系统软件。硬件包括计算机，ICETEK仿真器、ICETEK-VC5509-A系统板相关连线及电源，在设计上实现了系统的硬件电路小型化及模块化。软件采用C语言编程方式，根据系统设计的硬件电路及采用的控制策略，编写了相应的控制系统软件 关键词　DSP；电机控制系统；脉宽调制 Research on Motor Control Technology Based on DSP Abstract Motors play an extremely important role in multifarious electric drive and position servo systems．The aims of motor control are mainly speed and position control．With the fast development of power electronics，micro-electronics and materials ，the research of motor control recently becomes more and more important and the motor control system with high performance is updated ceaselessly．Motor control is on the way of digital and intergration especially when the DSP technologies which can combine the oneness of hardware with the flexibleness of software are applied to it．This thesis takes a stepper motor which have been used before in some projects for example realizes DSP solutions for the motors ． First of all，the thesis analyses the development and actuality of motor control system, indicates the commen existing problem，and introduces the characteristics of DSP solution for motors．Secondly，the basic elements and the operating principle of the stepper motor model is analyzed．The structure of control system and its control strategies are also resaerched in this thesis, at the same time， the design scheme of the syetem based on DSP is expounded. Thirdly，on the basis of the present outcome，the hardware and software of syetem based on TMS320C5 produced by TI Company are designedIn the hardware of system， Computer、ICETEK simulater、ICETEK-VC-5509-A syetem circuit、power line andpowersu
