ARM平台的矢量和PID交流电机控制系统

交流电机具有结构简单、制造容易、成本低、容易控制等等特点，在许多场合中逐步取代直流电机，成为电机使用者的首选，但是交流电机的调速系统复杂，在使用上很难达到和直流电机相媲美.文章设计一套基于ARM平台的矢量控制和PID算法的交流电机控制系统，实现对交流电机的精确的控制.系统分为硬件、软件、和上位机界面三部分，硬件电路包括电流采集电流和IGBT电路，软件部分采用C语言开发，使用KEI MDK软件开发工具编程，上位机采用LabVIEW软件编写测试界面，运行PID程序，最终开发出一套用于交流电机调速系统的电机控制.

Vector and PID AC Motor Control System on ARM Platform

The AC motor is simple in structure, easy in manufacture, low in cost, easy to control. It is gradually replacing the DC motor in many cases and becoming the first choice for motor users. However, the speed regulation system of AC motor is very complex. It is difficult to match DC motor. This paper designs an AC motor control system based on the ARM platform which makes use of Vector control and PID algorithm to control the AC motor exactly. The system has three parts:hardware, software, and the interface of the host computer. The hardware circuit includes current acquisition and IGBT circuit. The software part uses C language and KEI MDK software development tools to program. The upper computer uses the LabVIEW software to write the test interface and runs the PID program. Finally we develop a set of motor control for AC motor speed control system.
