【摘要】 一直以来,交流电机因为其非线性、时变性和变量之间的强耦合性,使得对交流电机的变频调速很困难,在很长一段时间内,电气传动都以直流电机为主。1971年德国学者提出的矢量控制原理从理论上解决了交流电机变频调速的难题,而随着现代电机制造技术、电力电子技术、微处理器技术的进步发展,尤其是各种新的大功率电子元件的出现,成为了交流电机变频调速系统实现的不可或缺的物理基础。而永磁同步电机(PMSM)又因为其本身的优点成为了在需要精确定位和各种小功率驱动场合的首选执行元件。本文在建立永磁同步电机矢量控制模型的基础上,进行了该调速系统的硬件和软件实现工作并进行了调速控制系统的软件仿真。研究并给出了永磁同步电机的矢量控制模型。采用TI公司的电机控制DSP芯片TMS320F2812为控制核心,进行了电机调速系统的硬件设计工作,给出了电机控制系统的电路原理图。采用TI公司的软件开发环境CCS2000进行电机调速系统的软件开发工作,给出了软件系统的总体结构图和各个子环节的流程图以及关键程序。最后用仿真软件Matlab/Simulink对该永磁同步电机控制系统进行仿真,并得出仿真结果,验证所采用的控制算法和系统结构的可行性和正确性更多还原

【Abstract】 For along time, because of the non-linearity, time-variety and heavy-coupling of the variable, it is difficult to control and change the rotate speed of the Alternating Current(AC) motor with variety of the frequency, Direct Current motor was used as the most important drive equipment in the much electric drive domain. The problem of the AC motor was solved with the appearance of the vector control theory in Germany in1970s. By the advancement of the technology in motor making, electric power and electron, microprocessor, especially lots of the new high-power electron elements, all of which become the physical foundation of the AC timing control system. Based on the itself characteristic, the Permanent Magnet Synchronous Machine(PMSM) will be the first drive equipment to orientate exactly and drive low-power machine.The mainly contents of this dissertation include the vector control theory, hardware and software of a PMSM AC control system and the emulating with the Matlab/Simulink. In this dissertation, we design the hardware system of the AC control system with the control chip:TMS320F2812 of the TI company and educe the circuit diagram of the control system; design the software system of the AC control system with the CCS2000 of the TI company and educe the soft flow charts and the key programme. Emulate the AC control system with the Matlab/Simulink in order to validate the correctness and feasibility of the control arithmetic and system’s configuration.更多还原
