摘要
针对伺服系统和调速系统中速度测量问题,介绍了M法、T法、M/T法三种电机测速方法的工作原理,并分析了其特点。在此基础上以TMS320F2812为基础研究了三种方法的程序设计,并对三种测速方法的程序进行了实验测试。以TMS320F2812作为控制芯片实现M/T法测速,在低速、中速和高速区都有高的测速精度,为伺服控制和调速奠定了基础。
The three operation theories of motor speed detection arithmetic called M arithmetic,T arithmetic and M/T arithmetic are presented,and their characteristics for the problem of speed detection in servo system and speed governing system are analyzed.Based on this,the programs of these three arithmetics have been achieved depending on TMS320F2812.And the experiments of these three programs have been done.It has high precision that TMS320F2812 is used to be the controlling chip for achieving speed detection with M/T arithmetic.And it lays the foundation for the servo control and speed governing.
