摘要
随着电力电子、微电子技术和控制技术的发展,一些场合对电机调速系统性能的要求越来越高,而锁相调速控制在稳速精度方面有其独特的优势。文章在改进的数字锁相环基础上,提出了软件锁相环电机速度控制系统,利用高性能微处理器实现了软件锁相环。
With the development of the electric power and electronics, micro- electronics technology and control technology, the performance of electromotor timing syetem is required higher and higher, so phase - locked timing control has its unique advantage in steady speed precision . Based on the improved digital phase - locked loops , the paper puts forward the velocity control system of electromotor with the software phase - locked loops , and the Software phase - locked loops is achieved by use of high - powered microprocessor software.
