| 中文摘要: |
| 目前，在数控机床、自动化生产线、工业机器人等应用场合，以永磁同步电机(PMSM)为控制对象的全数字交流伺服系统正逐步取代直流伺服系统。为了提高永磁同步电机控制器的控制性能，设计开发了基于飞思卡尔32位的MC56F84789型DSP的永磁同步电机数字化矢量控制器。MC56F8479包含各种先进的高速、高精度外设。文中介绍了PMSM的数学模型和磁场定向矢量控制原理，设计了一套功能完善、实时性好的PMSM交流伺服系统。实验结果表明电流环响应迅速、速度和位置闭环控制无稳态误差，所设计的系统工作可靠，控制速度快。 |

| At present, the digital AC servo system with permanent magnet synchronous motor(PMSM) is gradually replacing the DC servo system in the CNC machine tools，automatic production lines，industrial robots and other applications. In order to improve the performance of PMSM vector controller，a digital vector controller for PMSM based on Freescale 32 bit DSP MC56F84789 was designed. MC56F84789 contains a variety of advanced high speed, high precision peripherals. The mathematical model of PMSM and field oriented control principle were described. A PMSM servo system was designed with multi functions and good real time performance．The experimental results show that the current loop responds quickly, and there is no steady state error for speed and position closed loop control．The system is verified to be reliable and has fast control speed． |
