【摘要】 本文着重研究了交流永磁同步电动机的伺服控制，在交流感应电动机矢量控制和直流无刷电动机控制基础上，总结并提出了一种新的无电流环交流永磁同步电动机矢量控制思路、位置控制模型和算法及其软制动控制方式，利用TI推出的DSP芯片TMS320LF2407A，成功地实现了对小功率交流永磁同步电动机的伺服控制，包括速度控制和位置控制。由于时间问题，在负载波动较大情况下，控制系统的位置控制特性尚有差距，这个问题将会是进行进一步研究的重点。目前，国际上解决这个问题的方法主要是建立一个优秀的控制模型，并辅之优秀的控制算法，效果较为理想，并且应用较广泛的控制主要有模型自适应控制等。 本文共分为概述、正文(七章)、参考文献及录用文章说明等部分。 概述部分介绍了本课题的背景，该行业的一些龙头公司，提出了本课题的设计指标及创新思路。 第一章介绍了控制电机基础知识，包括控制电机的分类、基本要求等。 第二章对伺服控制理论作了一个简要介绍，包括伺服电机相关知识、伺服控制概念及交流永磁同步电机的矢量控制方法等。并且通过系统建模，利用Matlab实现了对系统模型的仿真分析。 第三章到第五章着重阐述了本课题的实施方案，主要包括软件部分和硬件部分。提出了基于DSP芯片TMS320LF2407A的交流永磁同步电机伺服控制方案，详细介绍了速度控制环节、位置控制环节的实现方案及其算法，并且给出了实验结果和分析。列表说明当前已经完成的工作及今后进一步工作的建议。 第六章简要介绍了该领域的国内外发展现状。 第七章作了结论和对今后的展望。 本文最后附上参考文献汇总和研究生学习期间的录用文章说明。更多还原

【Abstract】 The servo control of Permanent Magnet Synchronous Motor (PMSM) is the emphases of this paper. Based on summary of inductive motor’s Vector Control and BLDC’s control, it presents a new Vector Control idea, position control model and soft brake control without current loop of the PMSM. It’s proved successful on low power PMSM’s servo control based on the DSP chip TMS320LF2407A of TI, including speed control and position control. Till now, the characteristic of position control is not very good when load varies obviously, and this will be the emphasis of further research work. Now, the better choice to resolve this question is conducting an excellent control model with excellent control arithmetic. The Model Self-Adapt Control is proved successful and is adopted widely in the world.Summarization, main body (seven chapters), referrence literatures list in this paper and appendix of articles adopted are included.Background of this project, main companies in this field, target of design and innovation ideas are introduced in the summarization.The first chapter presents the knowledge of control motor, including the sorts and base requirements of control motor.The second chapter presents theory of servo control simply, including the relative knowledge of servo motor, conception of servo control and vector control of permenent magnet synchronous motor, etc. Furthermore, emulating of system model based on Matlab is realized.The third to the fifth chapter describes the scheme of this project detailedly, including software part and hardware part. It presents a scheme of servo control on permenent magnet synchronous motor based on DSP chip TMS320LF2407A. Speed control, position control and arithmetic are emphasized. Results of experiment and analysis are showed. And there is a list of finished work and advices for further work.The sixth chapter presents current status in this field simply.The seventh chapter draws a conclusion and prospects.At last, there are referrence literatures list and the appendix of articles adopted.更多还原
