摘要永磁同步电动机因其体积小、重量轻、损耗小、效率高的特点，在控制领域有着广泛应用。然而，与直流电动机相比，其数学模型较为复杂，因此，对永磁交流同步电动机的控制策略研究显得至关重要。 本论文对永磁同步电动机的结构进行了细致的研究，得到了其在三种不同坐标系下的数学模型，并利用其在 d-q 旋转坐标系下的数学模型简化了其电磁转矩方程式。针对此方程式，论文详述了基于控制电磁转矩的转速控制方案，并对产生圆形旋转磁场的 SVPWM空间矢量脉宽调制策略进行了深入研究。 基于对控制的硬件要求，论文构建了控制系统的整体硬件框图，并在此框图的基础上设计了基于 TMS320F2812 处理器芯片的控制板，分模块对其设计步骤进行了分析与解释。控制板完成后，作者利用 CCS3.1开发软件对此控制板进行了重要功能的调试工作，并对调试结果进行了简要分析。 同时，为了对本次设计所选择的控制策略进行验证，论文采用了 SIMULINK 作为仿真工具。在对各个仿真模块详细了解的基础上，作者搭建起整个控制系统，在系统空载与带载的情况下分别对系统进行了仿真。通过仿真得到的波形，论文分析了所选控制策略的实际效果。60449

Title   DSP-based PMSM controller design--part of hardware           
Abstract PMSMs are widely used in speed control area because they are small, light, with very low loss and high power. However, compared with dc motors, PMSMs have a much more complex mathematical model. Therefore, it is very important to study the control strategy of PMSMs.  The author has done a detailed study on the  structure  of PMSMs and got three mathematical models based on three coordinate systems. What’s more, a much more simplified formula of electromagnetic torque has been achieved. Based on this formula, the paper gives a specification on how to control the rotate speed and also gives a detailed explanation about the SVPWM theory. An overall block diagram of hardware is built based on the requirements for speed control, and a control panel based on TMS320F2812 is designed. Detailed steps of design are given in this paper. What’s more, some important functions of the panel have been tested and the reliability of this panel is proved. Meanwhile, for validating the control strategy adopted in this design, SIMULINK is used as the simulation tool. Based on a good knowledge of all blocks used in SVPWM, an overall control system is built and it is tested on no-load and with-load conditions. With wave forms generated in this simulation, the practical effect of the SVPWM control strategy is analyzed.
