【摘要】：70年代后期，，与电励磁电机相比永磁同步电机具有体积小、效率高、功率因素高等一系列优点而得到了科技研究人员和行业应用人员的广泛关注。相信在不久的未来，伴随着新的永磁材料被不断地开发利用，控制理论的不断完善发展，以及电力电子器件的不断进步，永磁同步电机的控制驱动技术会吸引越来越多的研究和应用。 论文是作者在对丰富的相关资料及文章广泛阅读的基础上，在对PMSM及其控制驱动技术的发展和趋势深入理解之后，在对电机的内部结构作出解析后分析了三相及两相不同坐标系并建立了永磁同步电机在三种不同坐标系下的数学模型，详尽地探究了PMSM的矢量控制策略。并且提出了在积分环节加入反馈的PI的电流滞环控制方案，在Matlab/Simulink环境下仿真表明其与使用常规比例积分PI的电流控制方案相比具有更快的转速和转矩响应。 在数学软件Matlab的系统建模、仿真组件Simulink环境下进行模拟仿真之后，搭建了在电流、转速采样电路、智能功率模块驱动电路、隔离电路，及电源电路等电路的基础上以TMS320C2812数字信号处理器DSP为核心，以智能功率模块IPM为驱动的系统对永磁同步电机进行控制。软件方面分析了程序的整体思路，主体结构及中断的执行流程，以及A/D转换、PI控制、PWM调制器等子程序的功能实现，叙述了矢量控制系统的控制流程，实现了控制系统的数字化智能控制。
[Abstract]:In the late 1970s, compared with the electric excitation machine, permanent magnet synchronous motor (PMSM) has a series of advantages, such as small size, high efficiency and high power factor, so it has been paid more attention by researchers and applications in the field of science and technology. It is believed that in the near future, along with the constant development and utilization of new permanent magnetic materials, the continuous improvement of control theory and the continuous progress of power electronic devices, The control drive technology of permanent magnet synchronous motor (PMSM) will attract more and more research and application. This paper is on the basis of extensive reading of the rich relevant data and articles, after the in-depth understanding of the development and trend of PMSM and its control-driven technology, After analyzing the internal structure of the motor, the three-phase and two-phase different coordinate systems are analyzed, and the mathematical models of the permanent magnet synchronous motor in three different coordinate systems are established. The vector control strategy of PMSM is discussed in detail. The current hysteresis control scheme of PI with feedback in the integral link is proposed. The simulation in Matlab/Simulink environment shows that the current control scheme with proportional integral PI has faster speed and torque response than that of the conventional proportional integral current control scheme. After the system modeling of the mathematical software Matlab and the simulation under the environment of Simulink, the sampling circuit of current and speed, the drive circuit of intelligent power module and the isolation circuit are built. Based on the TMS320C2812 digital signal processor (DSP) and the intelligent power module (IPM), the permanent magnet synchronous motor (PMSM) is controlled on the basis of the power circuit and other circuits. In the software aspect, the whole idea of the program, the main structure of the program and the execution flow of the interrupt are analyzed, and the function realization of the subroutine such as A / D conversion, PI control, PWM modulator, etc., and the control flow of the vector control system are described. The digital intelligent control of the control system is realized.
